A powerful coastal storm centered about 300 miles east of the Georgia coast continues to bring coastal flooding and significant beach erosion from North Carolina to southern Florida. Flood waters driven ashore by winds approaching tropical storm force closed the only road connecting North Carolina's Outer Banks to the mainland on Monday. The water over U.S. 12 just north of Rodanthe cut off a Warner Brothers movie crew filming "Nights in Rodanthe," which stars Richard Gere and Diane Lane. A lifeguard office and garage slid into the ocean at Jupiter Inlet, Florida, and about 100 feet of coastal road were underwater at 1:30 am Tuesday. A coastal flood warning remains in effect for much of the North Carolina coast, where a storm surge of 3-5 feet is expected today. High surf advisories are posted for the entire coast from Maryland to Miami. Winds of minimal tropical storm force (35 knots, or 39 mph) are occurring over a large stretch of ocean surrounding the storm, according to the latest QuikSCAT satellite wind estimates. The South Carolina buoy 41004 had 15 foot seas and sustained winds of 39 mph at 9am EDT this morning.


Figure 1. Model tracks for the Southeast coastal storm, now dubbed "Invest 90L" by NHC.


Figure 1. Visible satellite image of the May 8, 2007 coastal storm.

The coastal low moved over the core of the Gulf Stream (dark orange colors of Figure 3) last night, the warm waters it encountered helped intensify the storm to a central pressure of 1000 mb--which was not forecasted well by the computer models. The low is now a hybrid between a cold-cored Nor'easter and a warm-cored tropical storm, but does not have the characteristics needed to be called a subtropical storm. A subtropical storm has much heavier rains and more organized thunderstorm activity, which typically form a solid band of rainfall 100 miles or more from the center. Today's storm shows no evidence of bands of precipitation forming; the thunderstorm activity is disorganized. If a major organized band of thunderstorms does develop over the next day or two, the NHC could designate this storm as Subtropical Storm Andrea. I am not expecting that to happen, given the marginal SSTs (24-26 C), and significant amount of dry continental air surrounding the storm.

Cyclone Phase Space diagrams available at the Florida State University web site maintained by Dr. Bob Hart show that the storm has neither a cold nor a warm core, but is a hybrid. The model forecasts call for the storm to remain in this hybrid state until it makes landfall by Thursday morning, somewhere between the Georgia and South Carolina coasts. The storm should gradually decrease in strength, and winds have already dropped considerably from yesterday. Unfortunately, the storm has not acquired enough tropical moisture to be a big rain maker, and its winds are serving to fan fires in southern Georgia and northern Florida. I expect the storm will bring 1-2 inches of rain to South Carolina on Thursday, and lesser amounts to Georgia and northern Florida.

NHC issued this special advisory this afternoon:

SPECIAL TROPICAL DISTURBANCE STATEMENT
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
400 PM EDT TUE MAY 8 2007

A NON-TROPICAL LOW PRESSURE SYSTEM...CENTERED ABOUT 200 MILES SOUTHEAST OF THE GEORGIA AND SOUTH CAROLINA COASTS...HAS BEEN MOVING SLOWLY WESTWARD AT 5 TO 10 MPH. THE LOW IS PRODUCING GALE-FORCE WINDS NEAR THE COASTS OF NORTH CAROLINA...SOUTH CAROLINA...AND GEORGIA. THIS SYSTEM HAS CHANGED LITTLE SINCE THIS MORNING...AND NO SIGNIFICANT STRENGTHENING IS EXPECTED. THE LOW IS BEING MONITORED FOR SIGNS OF TROPICAL OR SUBTROPICAL CYCLONE DEVELOPMENT...AND AN AIR FORCE RESERVE RECONNAISSANCE AIRCRAFT WILL BE AVAILABLE TO INVESTIGATE THE SYSTEM TOMORROW MORNING...IF
NECESSARY.

INTERESTS ALONG THE COAST OF THE SOUTHEASTERN UNITED STATES SHOULD MONITOR PRODUCTS ISSUED BY LOCAL NATIONAL WEATHER SERVICE FORECAST OFFICES.

Severe weather in the Plains finally abates
The severe storm action finally quieted down yesterday in the Midwest, where no tornadoes were reported for the first time since Thursday. The severe weather action should stay at a slow simmer through Thursday over the Plains; the Storm Prediction Center (SPC) has portions of the region under its "Slight Risk" area for severe weather. Flooding continues to be a major concern over most of eastern Kansas, plus large portions of Oklahoma, Missouri, and Iowa. Although the heaviest rains are now over, river levels are still expected to rise in many regions through Thursday.

Global tropical cyclone record set
Today marks the 31st straight day without a tropical cyclone anywhere in the world, breaking the record for the longest such streak on record. Margie Kieper's View From the Surface blog has more details on this unusual event.

I'll have an update on Wednesday morning.

Larger Refineries taking chances and ignoring safety rules. Then all receive additional restrictions, which sometimes causes lower production.

I heard one report on the local news that, refineries had an unusually high amount of accidents and malfunctions this spring. I also heard they refine large quantities in cycles. I think they step up production in the spring and fall.
My dad is an engineer at a chemical plant in Lake Charles, La. Its not a refinery, but he has been there for 30yrs and know many of the people that work at refineries. He said the EPA has handicapped the system and pushed the cost of production up at least 30%. He said many of the regulations are redundant and don't make much sense.

In SE north carolina we have less than 3 tenths in 3 days of 20 mph weather. The wind is more calm today. Let it rotate back if thunderstorms are building.In case the Indians are reading, Richard Gere is stranded on the Outer Banks by overwash and cutting of the road. Maybe they will extridite.

Wind is picking up a bit here near Gainesville FL. In addition to all the smelly smoke we've been suffering the last week or so now ash from all the fires is being picked up and is coming down like snow. Feels like the last days of Pompei... At least I'm getting a nice application of potash on the gardens. Hope 90L brings some rain to wash that potash in!

One could have a Billion bbls..but still only a certain capability to refine it.

Very true. Saudia Arabia may have alot of oil to export, but they must IMPORT refined gasoline since they do not refine any. So having an oil well spouting oil will only grease your hair if you can't do anything with it.

I received this advisory this morning.

ALACHUA COUNTY ISSUES HEALTH ADVISORY FOR SMOKE

Due to the fires both in the county and in Georgia, we are
experiencing significant smoke and particulate matter in the
area. The Health Department, in concert with the Department
of Emergency Management, have issued a health advisory until
conditions improve.

The effects of smoke run from irritation of the eyes and
respiratory tract to more serious disorders, including asthma,
bronchitis, reduced lung function, and possibly death. Studies
have shown that the fine particulate matter contained in smoke
is linked with aggravation of existing respiratory and
cardiovascular problems. The extent of the health problems are
linked to the level of exposure, age, individual susceptibility,
and other potentially associated factors.

Individuals with asthma, cardiovascular disease, the elderly,
and children, should restrict their outdoor activities at
this time. Children, even those without preexisting conditions,
are considered a sensitive population because their lungs are
still developing. Of course, those individuals that smoke are
susceptible due to decreased lung function.

Citizens are asked to evaluate their health conditions and
limit their outside activities until conditions improve.

This system has no real deep convection around its center so in reality its still cold-core but its transition to sub-tropical storm has been under going and from the looks as i stated the NHC will probably go ahead and start anvisories on this system at 11am this morning.

"this was the last place I expected a storm to develop at this time of the year (as opposed to the traditional areas in the Southern Gulf)"

...actually, this is a pretty typical region for pre-season development. Since 1900 there have been 17 storms to develop in April or May. Only two have been in the Gulf (and NOT in the southern Gulf). Six have been off the U.S. East Coast (a few very similar to this one, a few a little further offshore). So, this is a pretty classic pre-season type of development. And, incidentally, in those 16 seasons (one season had two pre-season storms), the mean activity was normal. So, a pre-season storm is a harbinger of nothing. Some of the seasons were very active (1933), some were pretty quiet (1972).

Oil isnt the problem in America folks. Its refining capacity. Lotsa refineries do Catcracker maintenence in the Spring. Those units produce the gasoline . We havent built a new refinery in 32 years in America. One could have a Billion bbls..but still only a certain capability to refine it. Thanks to Fed regulations and EPA guidelines. No one can build a new refinery. Its cost prohibitive.

The overall point is whether the NHC names it or not, its weak, and it doesn't matter that much.

My personal thought is the NHC is going to be more carefull to name weak storms that aren't capable of much.

I'm hoping people are preparing for the 2007 hurricane season.

I'm preparing for $5 a gallon gas as soon as a hurricane gets in the gulf...which seems almost likely from everything I've read.

By the way, effects from a non tropical system on one of the subtropical or tropical alot different not the same.

As Jeff Masters said, subtropcal systems have ALOT more moisture and much deeper convection.

PWATS withing systems containing tropical characterists are often have at least 3 times as much availble moisture as los of the non tropical type.


So there would clearly be a difference, convection would be deeper, and tropical systems are far wetter than any non tropical ones are.

What happened to following the Expert herd of sheep?



Theres only one big issue, where did I say it WON'T have any chance of changing over? Thats right, that would be no fella, I said its almost there and it has a chance, it just isn't there yet.

Well today it is, and if the NHC doesn't name it, they've just gotten much pickyer on how they name storms that have converted from extratropical to sub-tropical or tropical.
