Tropical Cyclone Rusty rumbled ashore over the coast of northwest Australia near 06 UTC (1 am EST) on Wednesday near the small town of Pardoo, about 110 km east of the largest city in the region, Port Hedland. Rusty peaked at Category 2 strength with 110 mph winds about 12 hours before landfall, but weakened to a Category 1 storm with 90 mph winds as it approached the coast, due to interaction with land. Sustained winds as high as 55 mph, gusting to 74 mph, were observed observed at the Port Hedland airport as Rusty made its approach. Rusty has dumped over 7" of rain on the coast, and major flooding is expected on area rivers. No casualties and only minor damage have been reported thus far, and I expect total damage from the storm will be less than $100 million. Rusty is the strongest tropical cyclone to affect Australia so far in the 2012 - 2013 tropical cyclone season.

Significant snowstorm continues over Midwest U.S.
Meanwhile, back in the U.S., the second major winter storm in a week continues to blanket the Midwest with significant snows. The snowstorm, dubbed "Rocky", gave Chicago 5.4" of snow, its heaviest snowfall of what has been a quiet winter. According to the latest NOAA Storm Summary, the heaviest snow in the Midwest from Rocky fell in the Texas Panhandle, where 21" was measured in Follett. While the precipitation from the two major winter storms during the past week will not come anywhere close to busting the Midwest drought, the moisture they dropped is probably worth billions to agriculture.

TROPICAL CYCLONE RUSTY, CATEGORY ONE (10U)
11:42 AM WST February 28 2013
=======================================

At 11:00 AM WST, Tropical Cyclone Rusty (987 hPa) located at 21.7S 120.5E or 100 km southeast of Marble Bar and 200 km north northeast of Newman has 10 minute sustained winds of 35 knots with gusts of 50 knots. The cyclone is reported as moving south southeast at 8 knots.

Tropical Cyclone Rusty continues to weaken as it moves in a south to southeasterly direction over the inland east Pilbara. Rusty is expected to weaken below cyclone strength during Thursday afternoon.

DAMAGING winds with gusts up to 50 knots are possible. Gales may affect Nullagine until mid afternoon, and possibly reach Newman before Rusty weakens below cyclone intensity.

MAJOR FLOODING is occuring in the De Grey catchment, and heavy rainfall is likely to continue.

Tropical Cyclone Warnings
===========================
The Cyclone WARNING for Marble Bar has been cancelled

You need to add a faint line from each mph section so it make it easier to read. Also it's not ABM it's BOM(Bureau of Meteorology) or if you want ABOM (Australian Bureau of Meteorology)

Also you could use a world map as background as it is a Tropical Cyclone Classification table from world wide basins.

All in all, nice job.

Rain on the sun

By Tom Yulsman | February 27, 2013 2:40 pm

NASA recently released this video of a phenomenon called “coronal rain.” It is astonishingly beautiful, and the scale of it is simply mind-boggling.

If you haven’t already seen it elsewhere (it has been making the rounds on Youtube), it’s well worth stopping what you’re doing and taking a look.

Obviously, coronal rain isn’t the liquid stuff that we experience here on Earth. Instead of water, it consists of plasma in the sun’s corona.

Because plasma is electrically conductive, it responds strongly to magnetic fields. And in the case of coronal rain, the plasma cools, condenses and aligns along solar magnetic field lines. This is what produced the incredible filamentary looping structures seen in the video.


According to NASA, this event was particularly noteworthy. Here’s an excerpt from the agency’s description of what happened:

Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun’s atmosphere, the corona.

On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun’s lower right limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays – a phenomenon known as coronal rain.

NASA has released the first full year of validated ocean surface salinity data from the agency's Aquarius instrument aboard the Aquarius/SAC-D spacecraft. The data cover the period from Dec. 2011 through Dec. 2012. Red colors represent areas of high salinity, while blue shades represent areas of low salinity. Among the prominent salinity features visible in this view are the large area of highly saline water across the North Atlantic. This area, the saltiest anywhere in the open ocean, is analogous to deserts on land, where little rainfall and much evaporation occur. Aquarius is a focused effort to measure ocean surface salinity and will provide the global view of salinity variability needed for climate studies. The mission is a collaboration between NASA and the Space Agency of Argentina (Comision Nacional de Actividades Espaciales). Image credit: NASA/GSFC/JPL-Caltech - See more at:

Great news! In a statement on Wednesday night, Shell said it would pause its exploration drilling activity for 2013 in Alaska's Beaufort and Chukchi Seas to prepare equipment and plans for a resumption of activity at a later stage. It did not specify a likely resumption date.

As well as damage to the Kulluk, Shell faced another setback when the US Coast Guard found regulatory violations, including fire hazards, on its other Arctic drilling rig, the Noble Discoverer. These have been passed to the US Department of Justice to consider possible penalties.

Tropical Cyclone Warning Center Perth
Tropical Cyclone Advice #39
TROPICAL CYCLONE RUSTY, CATEGORY ONE (10U)
8:52 AM WST February 28 2013
=======================================

At 8:00 AM WST, Tropical Cyclone Rusty (982 hPa) located at 21.1S 120.4E or 65 km east of Marble Bar and 260 km north northeast of Newman has 10 minute sustained winds of 45 knots with gusts of 65 knots. The cyclone is reported as moving south southeast at 6 knots.

Gale Force Winds
=================
10 NM from the center in northwestern quadrant
40 NM from the center in northeastern quadrant
40 NM from the center in southern quadrants

Dvorak Intensity: OVERLAND

Tropical Cyclone Rusty continues to weaken as it moves in a south to southeasterly direction over the east Pilbara. Rusty is expected to weaken below cyclone strength during the day.

DAMAGING winds with gusts up to 65 knots are possible near the center, though these maximum winds will ease during the day. Gales may extend to Nullagine this morning and possibly to Newman during the afternoon before Rusty weakens below cyclone intensity.

Tropical Cyclone Warnings
===========================
A Cyclone WARNING is current for Inland areas of the eastern Pilbara, northeastern Gascoyne and adjacent parts of the Interior, including Nullagine and Newman.

Forecast and Intensity
========================
12 HRS: 23.4S 120.5E - 30 knots (Tropical Low)
24 HRS: 25.9S 120.1E - 25 knots (Tropical Low)
48 HRS: 31.0S 121.5E - 20 knots (Tropical Low)
72 HRS: xx xx - xx

Additional Information
=======================
Final intensity estimate has been lowered to 45 knots 10-min mean wind based on a standard weakening rate over land.

Over the last few hours the system has been moving in a south to southeasterly direction. Tropical Cyclone Rusty will continue to weaken as it moves further inland today and is expected to be below cyclone intensity during Thursday afternoon.

Heavy rain has become confined to areas south of the low level circulation center with strongest winds also expected to be on the southern side under the deeper convection.

Major flooding in the De Grey remains a concern. Significant flooding is also possible in the Upper Fortescue catchment and in Pilbara coastal streams, though a strong gradient in rainfall is likely to the west of the track.

After doing some research, there have only been a handful of tropical cyclones across the world, during the entirety of recorded history, to produce more rainfall than Hurricane Flora.

The November 1909 Greater Antilles hurricane produced a maximum rainfall total near 135 inches on Jamaica.



Typhoon Morakot, just recently in 2009, produced 120.5 inches of rain in Alishan, Chiayi.



And finally, Super Typhoon Carla in 1967 produced 108.21 inches of rain in Hsin-Liao.

There's a reason Hurricane Flora is considered the wettest known tropical cyclone to hit Haiti. The unimaginable amount of rain that fell on the country is also why Flora is known to be one of the deadliest Atlantic hurricanes on record; over 7100 were killed, the fifth or sixth deadliest on record.

It sounded like that was an offensive comparison for you VR46L by the way... did I misunderstand?


I saw what you meant...but also meaning, only could compare with N FL though I reckon too?
