There never was an easier major 'cane to prepare for than Jeanne. Mainly, since everything had been done for Frances & we were still too tired to have undone much, well that & we spent a little of the few weeks of the inbetween time in Ivan's cone of doom. Lesson learned~ there is certain outdoor matainance & landscaping you do every year. Some you may as well do at the beginning of 'cane season.

Cut & Clear...
~Cut down large dead limbs & trees.
~Cut down sickly trees (many of these will die a few days to a week before a storm anyways).
~Cut back limbs that would hit a structure in a high wind.
~Clear canals & ditches of excess brush & trash.
~This saves you so much time that right before a 'cane hits mow your lawn extra short this helps leaves & debri roll into you nieghbors' yard & shortens your clean up time.

Make a list
~Tour your yard & note the things that would need put away or tossed in the pool. I do a good barn & shed cleaning so there is room to stow the stuff too. Putting up those extra yard idems that aren't used so much in the heat of the summer is good to do as well.

Pick your plants & your fencing
~Anytime you put in new plants native will give you less mess after a storm & be more likely to survive, as well as not land on your house & what not. A few others do well too.
Good plants
~hibiscus, roses, plumbagos, bulganvilia, butterfly plants, roses, palmettos, azalea, jasmine, creeping fig, citrus, live oak, Magnolias.

Bad trees
~Ear trees, queen palms.

~always consider the salt tolerances for your area & consult with a native nursery guy.
~Consider how big a tree can get before you chose where to plant it.

For fences pick sturdy stuff that air flows through. Reinforce gates & besure with privacy fence gates to open them all the way back up against the fence & secure them with nails or screws before a major wind.

Updated June 7th~ The monthly is out. There take is possible for La Ni�a conditions in 1-3 months.

Regions 1&2 dropped this week, regions 3 & 3,4 stayed the same & region 4 rose.

The latest weekly SST departures are negative in the Ni�o 1+2 (-1.9oC) and Ni�o 3 (-0.6oC) regions, and remain near zero in the Ni�o 3.4 (0.0oC) and Ni�o 4 (+0.4oC) regions (Fig. 2).

We are still barely on the cool side of neutral

CPC summary say La Nina conditions possible in the next 1-3 months.

Nearly all of the model forecasts predict below-average SSTs in the Ni�o 3.4 region (5oN-5oS, 120-170oW) during the remainder of the year. Most statistical models show ENSO-neutral conditions persisting through August 2007, while most dynamical models indicate La Ni�a will develop within the next three months. Some forecast models, especially the NCEP Climate Forecast System (CFS), continue to predict a rapid transition to La Ni�a by July 2007. However, for the past few months the CFS forecasts have been predicting a stronger and more rapid cooling than has actually occurred. Historically, the next few months are a favorable period for the development of La Ni�a.

Barry brought enough rain to put FL in the average to above average rainfall for the last 30 days.

ESPI rose from -0.39 to -.04 for the last weeks for the last 30 days. I expect to see the moderation trend continue for the short term with more cooling after.

Insolation rip next to the tiles on the shuttle. No grave danger, they'll be looking into it. Similiar insidance on STS-114

Yeah wab, that's where that came from. I wanna say it's a classified military launch. The importance was greater than the shuttle's to the point had the shuttle been delayed too long it would had been resceduled to after the Atlas one.

Power flickered here when this one past, we had a severe t-storm warning at the time. At one point we had near 3000 lightning striks in an hour in the ECFL area. It's died down here now.

Several reports of funnel cloud hail & T-Storms damage out tof the Tallahasee office for NFL & GA.

I can't believe how fast they got the TRMM animations out on Gonu. It took near a month in 2004, better part of a week in 2005. They are pretty neat to stare at.

I'll be taking pics of the launch. & yeah posted some pics of the hail that nailed the shuttle. Maybe it's just the hail that crept into the subconscience~ I'm not the only one I know that has had nightmares about this launch.

The National Weather Service in Melbourne has reissued the

* urban and small stream flood advisory for...
Osceola County in east central Florida...

this includes the cities of... celebration... West Lake toho...
Saint Cloud... Narcoossee... Kissimmee... Intercession City...
Holopaw... East Lake toho... Lake Marian...

* until 1045 PM EDT

* at 844 PM EDT... Weather Service Doppler radar indicated very heavy
rian continuing to fall over the western half of Osceola County with
Road closures reported in the Saint Cloud area by local fire Rescue
personnel. Additional rainfall amounts of one half to one inch are
expected in the advisory area before the rainfall finally ends.

A flood advisory means heavy rainfall is causing or is likely to
cause ponding of water in urban areas and elevate river or stream
flows. Minor flooding may cause temporary Lane or Road closures but
the threat of water entering homes and businesses is low.

Excessive runoff from heavy rainfall will cause temporary flooding of
urban areas... such as Highways... streets and intersections as well as
poor drainage areas and low lying spots.

Do not drive your vehicle into areas where the water covers the
roadway. The water depth may be too great to allow your car to cross
safely. In addition... motorists should deactivate cruise control in
heavy rainfall to reduce the risk of hydroplaning.

To report flooding... have the nearest law enforcement agency relay
your report to the National Weather Service forecast office.

It came right down to the last hour, but late this afternoon, NASA cleared the shuttle Atlantis for launch on Friday.
NASA said they are worried about the current weather.

"If it hails again, we'd be so unlucky," said launch Director Mike Leinbach.
Pounding rain carries the threat of hail.

Another hailstorm would keep NASA's impressive streak of bad luck alive, and even if there's no damage, it would kick off such an extensive round of safety inspections that the launch could be delayed.
Never before has a shuttle taken off with so much damage to its tank, speckled with 4,000 patches from the February hailstorm.

"We're ready to go," said Leinbach.

Didn't you have pics of this hailstorm Skye? ... and, YIPES!?

RARE CYCLONE BRUSHES ARABIAN PENINSULA

At one time Cyclone Gonu was a powerful Category 5 storm packing sustained winds of 160 mph, according to the Joint Typhoon Warning Center, and on a course for Oman. This made it the most powerful cyclone ever to threaten the Arabian Peninsula since record keeping began back in 1945. Fortunately the storm weakened significantly by the time it brushed the far eastern tip of Oman.

Tropical cyclones do on occasion form in the Arabian Sea, but they rarely exceed tropical storm intensity. Last year, Tropical Storm Mukda was the only system to form in the region, and it remained well out to sea before dissipating. Gonu became a tropical storm on the morning (local time) of 2 June 2007 in the east-central Arabian Sea. After some initial fluctuations in direction, the storm settled on a northwesterly track and began to intensify. Gonu went from tropical storm intensity on the morning of the the 3rd to Category 2 on the night of the 3rd. By daybreak on the 4th, Gonu was up to a Category 4 storm with winds estimated at 115 knots (132 mph).



The Tropical Rainfall Measuring Mission (TRMM) satellite was placed into low-earth orbit in November of 1997 with the primary mission of measuring rainfall from space; however, it has also proven to be a valuable platform for monitoring tropical cyclones, especially over remote parts of the open ocean. TRMM captured this image of Gonu as it was moving northwest through the central Arabian Sea. The image was taken at 03:23 UTC on 4 June 2007. It shows the horizontal distribution of rain intensity looking down on the storm. Rain rates in the center of the swath are from the TRMM Precipitation Radar (PR), while those in the outer portion are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). TRMM reveals the tell tale signs of a potent storm. Not only does Gonu have a complete, well-formed, symmetrical eye surrounded by an intense eyewall (innermost red ring), this inner eyewall is surrounded by a concentric outer eyewall (outermost red and green ring). This double eyewall structure only occurs in very intense storms. Eventually the outer eyewall will contract and replace the inner eyewall.



The next image shows a unique 3D perspective of Gonu using data collected from the TRMM PR from the same overpass as the previous image. Higher radar echo tops are indicated in red. The areas of intense rain in the previous image are associated with deep convective towers both in the innermost eyewall and in parts of outer eyewall. The inner ring has the higher tops at this time. Deep convective towers near the storm's center can be a precursor to future strengthening as they indicate that large amounts of heat are being released into the storm's core. At the time of these images Gonu was a Category 4 cyclone. Several hours after these images were taken, Gonu reached Category 5 intensity.

The system finally began to weaken during the night of the 4th and was downgraded to a Category 3 storm at 12:00 UTC on the 5th. Gonu continued to weaken as it neared the coast of Oman. The center remained just offshore of the northeast coast of Oman as a Category 1 storm before turning northward towards Iran where it is expected to make landfall as a tropical storm.

Tropical Cyclone Gonu


A storm with near-perfect symmetry and a well-defined eye hovering over the warm waters of the Caribbean or in the South Pacific is not unusual, but Tropical Cyclone Gonu showed up in a rather different place: the Arabian Sea. Though rare, cyclones like Gonu are not unheard of in the northern Indian Ocean basin. Most cyclones that form in the region form over the Bay of Bengal, east of India. Those that take shape over the Arabian Sea, west of the Indian peninsula, tend to be small and fizzle out before coming ashore. Cyclone Gonu was a rare exception. According to storm statistics maintained on Unisys Weather, the last storm of this size to form over the Arabian Sea was Cyclone 01A, which tracked northwest along the coast of India between May 21 and May 28, 2001. Unlike Gonus forecasted track, Cyclone 01As path never brought it ashore.

At 9:35 a.m. local time (06:35 UTC) on June 5, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Terra satellite captured this image, Tropical Cyclone Gonu was approaching the northeastern shore of Oman. At this time, the powerful storm had reached a dangerous Category 4 status. Sustained winds were measured at 250 kilometers per hour (155 miles per hour) according to the University of Hawaiis Tropical Storm Information Center, at the time of this MODIS image. The storm has the hallmark tightly wound arms that spiral around a well-defined, circular eye. The eye is surrounded by a wall of towering clouds that cast shadows on the surrounding clouds. Called hot towers, these clouds are a sign of the powerful uplift that feeds the storm. The symmetrical spirals, distinct eye, and towering clouds are all features regularly seen in satellite images of other particularly powerful cyclones, which are also known as typhoons or hurricanes when they form in other parts of the world.

The forecast as of June 5 called for the storm to graze Omans shore, but with the center of the storm staying offshore in the Gulf of Oman. The storms first landfall was predicted to be in southern Iran. The cooler water along the Oman coast was expected to rob the storm of some of its intensity, and it was predicted to strike the Iranian coast at around Category 1 strength. If, however, the forecast track is not quite right and the storm stays farther from shore over shallower and much warmer waters in the Gulf of Oman, it could make landfall while still packing Category 3 winds. In either case, communities along the Gulf of Oman are poorly prepared for hurricanes, given their rarity, and severe damage to cities and oil platforms is possible due to winds and storm surge.

The high-resolution image provided above is at MODIS full spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Tropical Cyclone Gonu

Varying wind speeds within the storm form a bulls-eye of color, with the highest wind speeds shown in purple in the center of the storm and gradually decreasing speeds radiating outward. Wind direction is depicted with small barbs. White barbs point to areas of heavy rain.

You might expect to see such a well-developed storm hovering over the warm waters of the Caribbean or in the South Pacific, but Tropical Cyclone Gonu showed up in an unusual place. On June 4, 2007, when it was observed by the QuikSCAT satellite, Cyclone Gonu was approaching the northeastern shore of Oman, a region better known for hot desert conditions.

Though rare, cyclones like Gonu are not unheard of in the northern Indian Ocean basin. Most cyclones that form in the region form over the Bay of Bengal, east of India. Those that take shape over the Arabian Sea, west of the Indian peninsula, tend to be small and fizzle out before coming ashore. Cyclone Gonu is a rare exception. As of June 4, 2007, the powerful storm had reached a dangerous Category Four status, and it was forecast to graze Omans north-eastern shore, following up the coastline on the Gulf of Oman. According to storm statistics maintained on Unisys Weather, the last storm of this size to form over the Arabian Sea was Cyclone 01A, which tracked northwest along the coast of India between May 21 and May 28, 2001. Unlike Gonus forecasted track, Cyclone 01A never came ashore.

Measurements of the wind strength of Cyclone Gonu show sustained winds significantly higher than those shown by QuikSCAT observations. QuikSCAT employs a scatterometer, which sends pulses of microwave energy through the atmosphere to the ocean surface, and measures the energy that bounces back from the wind-roughened surface. The energy of the microwave pulses changes depending on wind speed and direction, giving scientists a way to monitor wind around the world. This technique does not work over land, but allows measurements in storms over oceans.

Tropical cyclones, however, are difficult to measure. To relate the radar energy return to actual wind speed, scientists compare measurements taken from buoys and other ground stations to data the satellite acquired at the same time and place. Because the high wind speeds generated by cyclones are rare, scientists do not have corresponding ground information to know how to translate data from the satellite for wind speeds above 50 knots (about 93 km/hr or 58 mph). Also, the unusually heavy rain found in a cyclone distorts the microwave pulses in a number of ways, making a conversion to accurate wind speed difficult. Instead, the scatterometer provides a nice picture of the relative wind speeds within the storm and shows wind direction.
