Hurricane Season - 2011


Recommended Posts

The 5 p.m update for Don and it indicates that Don might be a touch less intense than the forecast at 11:00 a.m. today. It should be providing some rain to those of you east of where landfall is. Houston and Galveston are getting rain, but what's interesting is the intensity of the storm is to the the southwest, 210 degress, towards Brownville, Normally the worst side of a hurricane is the northeast quadrant?

TROPICAL STORM DON DISCUSSION NUMBER   9
NWS NATIONAL HURRICANE CENTER MIAMI FL AL042011
400 PM CDT FRI JUL 29 2011

SATELLITE IMAGERY SHOWS THAT DON REMAINS A SHEARED SYSTEM THIS
AFTERNOON...WITH THE LOW-LEVEL CENTER NEAR THE NORTHEASTERN EDGE OF
A DISORGANIZED MASS OF STRONG CONVECTION. AN AIR FORCE RESERVE
HURRICANE HUNTER PLANE MEASURED 56 KT FLIGHT-LEVEL WINDS AT 850 MB
AND ESTIMATED SURFACE WINDS OF 46 KT WITH THE SFMR...BOTH IN THE
NORTHEASTERN QUADRANT. BASED ON THIS...THE INITIAL INTENSITY
REMAINS 45 KT. IT SHOULD BE NOTED THAT DOPPLER WIND DISPLAYS FROM
THE BROWNSVILLE WSR-88D HAVE RECENTLY SHOWN A WELL-DEFINED
MESOCYCLONE IN A STRONG CONVECTIVE CELL WELL TO THE SOUTHWEST OF
THE CENTER AND THE PRIMARY CONVECTION.

THE INITIAL MOTION IS 300/14. DEEP-LAYER RIDGING OVER THE
SOUTHEASTERN UNITED STATES SHOULD STEER DON GENERALLY
WEST-NORTHWESTWARD UNTIL DISSIPATION. THE FORECAST TRACK CALLS FOR
THE SYSTEM TO MAKE LANDFALL BETWEEN BROWNSVILLE AND CORPUS CHRISTI
IN THE NEXT 12 HR...FOLLOWED BY A MOTION ACROSS SOUTH TEXAS INTO
NORTHEASTERN MEXICO. THIS FORECAST TRACK IS AN UPDATE OF THE
PREVIOUS TRACK.

EVEN THOUGH THE 12 HR FORECAST POINT SHOWS WEAKENING...THERE IS
STILL AN OPPORTUNITY FOR DON TO STRENGTHEN A LITTLE IN THE FEW
HOURS REMAINING BEFORE LANDFALL. THEREAFTER...THE CYCLONE SHOULD
STEADILY WEAKEN AS IT CROSSES SOUTHERN TEXAS...AND IT IS FORECAST
TO DISSIPATE OVER NORTHEASTERN MEXICO BY 48 HR.

FORECAST POSITIONS AND MAX WINDS

INIT 29/2100Z 26.9N 96.2W 45 KT 50 MPH
12H 30/0600Z 27.5N 98.0W 40 KT 45 MPH...INLAND
24H 30/1800Z 28.2N 100.6W 30 KT 35 MPH...INLAND
36H 31/0600Z 28.8N 103.3W 20 KT 25 MPH...POST-TROP/REMNT LOW

The storm in the Atlantic is now a 50% chance. There are a few more systems forming up in Africa which is very typical for this time of year. All of them 5 - 7 days apart and subject to whatever winds or air masses are presently in North America.

Corpus got nadda. I hit about 15 seconds of rain a little SE of San Antonio and when we arrived on the island about 19:45 it was all clouds and the typical afternoon wind.


High tides and heavy surf; folks are riding the waves but no boats out.

It does not look good, Texas is so dry the rain on radar looks like it's drying out as it hit's land. [:|]

It looks like it's going so fast it can't build up even a good rain.

This pretty much says it all. Too bad you gentlemen didn't get any rain. We finally got some this week after almost no rain for three and a half weeks.

400 AM CDT SAT JUL 30 2011

THE DON IS DEAD. THE CYCLONE LITERALLY EVAPORATED OVER TEXAS ABOUT
AS FAST AS I HAVE EVER SEEN WITHOUT MOUNTAINS INVOLVED. DON HAS NO
CONVECTION...MEAGER RAINFALL...AND ONLY A SLIGHT SIGNATURE IN
SURFACE OBSERVATIONS AND RADAR DATA. THEREFORE...THIS IS THE LAST
ADVISORY ON THIS SYSTEM. DON SHOULD OPEN UP INTO A TROUGH LATER
TODAY AS IT MOVES TO THE WEST-NORTHWEST AND IS NOT EXPECTED TO POSE
A RAINFALL THREAT.
The one out in the Atlantic looks like it could become Emily.
1. SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A LARGE LOW PRESSURE
SYSTEM LOCATED ABOUT 900 MILES EAST OF THE WINDWARD ISLANDS ARE
GRADUALLY BECOMING BETTER ORGANIZED. SURFACE PRESSURES REMAIN LOW
IN THE AREA...AND ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR A
TROPICAL DEPRESSION TO FORM OVER THE NEXT COUPLE OF DAYS. THIS
SYSTEM HAS A HIGH CHANCE...70 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES WEST-NORTHWESTWARD AT
15 TO 20 MPH.
There are another two storms over Africa, one just about to leave the coast and another following behind.

What a wimp, this Don.

NOAA seemed really tentative and confused. Rare they admit the situation is so complex they are clueless. We got some showers and locally heavy rains from it...probably a half inch. I don't thing anyone got more than a couple of inches for it and it was being considered a possible Allison comparable for Houston just three days ago.

The strong easterlies that tore Don apart seem to continue to prevent our normal sea showers, though my house has been getting more rain that normal for July.

If the GOM doesn't busy up pretty soon the forecasts for this year aren't going to do much to improve faith in long term forecasting.

TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

200 AM EDT SUN JUL 31 2011

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. SATELLITE IMAGES AND BUOY DATA INDICATE THAT THE LARGE LOW PRESSURE

SYSTEM CENTERED ABOUT 675 MILES EAST OF THE LESSER ANTILLES IS

CONTINUING TO BECOME BETTER ORGANIZED...AND IT COULD BE CLOSE TO

BECOMING A TROPICAL DEPRESSION. THIS SYSTEM HAS A HIGH CHANCE...

NEAR 100 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT

48 HOURS AS IT MOVES WEST-NORTHWESTWARD NEAR 15 MPH. TROPICAL

CYCLONE WATCHES OR WARNINGS WOULD LIKELY BE REQUIRED FOR PARTS OF

THE LESSER ANTILLES IF THE LOW BECOMES A TROPICAL CYCLONE LATER

TODAY...AND INTERESTS IN THESE AREAS SHOULD CLOSELY MONITOR THE

PROGRESS OF THIS SYSTEM. AN AIR FORCE HURRICANE HUNTER AIRCRAFT IS

SCHEDULED TO INVESTIGATE THIS DISTURBANCE LATER THIS AFTERNOON.

The latest on Invest 91 (Emily). It's projections have it getting closer to Miami, but still off the coast in all but one of the projections. This will still lead to a good amount of rain, so it bares further monitoring. At present, the storm has a 90% of becoming a tropical storm.

800 AM EDT MON AUG 1 2011

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. THE VIGOROUS LOW PRESSURE SYSTEM LOCATED ABOUT 300 MILES EAST
OF MARTINIQUE IS SHOWING SOME SIGNS OF IMPROVED ORGANIZATION...AND
A TROPICAL DEPRESSION COULD FORM LATER TODAY. THIS SYSTEM HAS A
HIGH CHANCE...90 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING
THE NEXT 48 HOURS AS IT MOVES WEST-NORTHWESTWARD AT AROUND 15 MPH.
A HURRICANE HUNTER AIRCRAFT IS CURRENTLY INVESTIGATING THE
DISTURBANCE TO DETERMINE IF IT HAS A WELL-DEFINED SURFACE
CIRCULATION CENTER. IF THE SYSTEM BECOMES A TROPICAL CYCLONE
TODAY...TROPICAL STORM WARNINGS WOULD BE ISSUED FOR PORTIONS OF
THE NORTHERN WINDWARD ISLANDS AND THE LEEWARD ISLANDS ON VERY
SHORT NOTICE. INTERESTS IN THESE AREAS SHOULD CLOSELY MONITOR
THE PROGRESS OF THIS SYSTEM. REGARDLESS OF TROPICAL CYCLONE
DEVELOPMENT OF THIS SYSTEM WILL BRING LOCALLY HEAVY RAINFALL AND
GUSTY WINDS TO PORTIONS OF THE LESSER ANTILLES TODAY AND TONIGHT.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

Well..... It has shifted and has the same characteristics (track paths, speed, environment, etc.) as Hurricanes Frances and Jeanne; Frances caused $30k worth of damage to my house because the inner "bands" have little embedded tornados.... It also did not help that the eye walls passed directly over my house....

Frances was the "pee bringer". It was one of largest storms on record. At it's peak it was the size of Texas, and slowed down to 3-5 mph. It lasted for almost 30 hours. Although "only" a strong Cat-1 (winds were about 85-90 mph), the fact that those particularly high winds lasted for 16 hours, things start to come apart from the vibrations, etc.

I have a complete new roof (early 2005), and new high speed Miami Dade Code (Cat-3+ impact resistant) aluminum track panel shutters, and the trees are in much better shape and bigger than in 2004-2005.

So... Given Murphy's Law, off to buy water, generator fuel and generator final testing this week, install the panels (which only takes about an hour [Y]), and get ready for the show. If it is going to be a direct hit, then all furniture opposite a window is moved into the center of the room(s), two 5 gallon buckets, an about 10 towels per window are stached ready to go, along with the mops and mop buckets strategically placed anywhere a potential problem can occur.

The biggest threat with a Cat-2 are the ridge vents. They are the new low profile design and supposedly can take 120 mph, and the roof was just inspected and "maintenanced by the roof builder. But if one of them lets go, then water comes flying through that ridge gap and can get into the ceiling and walls unless I can get up there in the attic with a nail gun and some plywood strips (which I happen to have ready...). Last thing I do before the power goes out (and you know when that's gonna' happen..... starts flickering and then blackness..). is run the air compressor to make sure I have enough air for the gun, and open the attic access door.....

I hate it when this crap happens.....

Well CRUD!!!

If it follows that red track it'll be in my back yard too. Coming in from that direction means I have to brace my garage door in addition to boarding up.

Think POSITIVE Take the blue track... Take the blue track... Take the blue track...

The link I posted above is the evolving one, it changes over time, instead of the static ones I posted before. This morning, Florida looked like it might have some rain off the coast, six hours later it looks like it might be time to make preparations and get the necessary wood, food, water, etc... to get you though what might happen. At the moment its moving at 15 - 20 mph which is good news compared to Frances. I'm sure that the track will change a few more times in the next week before it hits Florida or hopefully not.

200 PM EDT MON AUG 1 2011

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. SHOWERS AND THUNDERSTORMS EXTEND FROM THE LESSER ANTILLES EASTWARD
FOR A FEW HUNDRED MILES IN ASSOCIATION WITH A VIGOROUS TROPICAL
WAVE. AN AIR FORCE RESERVE RECONNAISSANCE AIRCRAFT IS CURRENTLY
INVESTIGATING THE DISTURBANCE...ALTHOUGH SATELLITE IMAGERY
INDICATES THIS SYSTEM HAS NOT BECOME ANY BETTER ORGANIZED SINCE
THIS MORNING. THE WAVE IS PRODUCING WINDS TO NEAR TROPICAL STORM
FORCE...AND ENVIRONMENTAL CONDITIONS REMAIN CONDUCIVE FOR A
TROPICAL DEPRESSION OR A TROPICAL STORM TO FORM LATER TONIGHT OR
TUESDAY. THIS SYSTEM HAS A HIGH CHANCE...80 PERCENT...OF BECOMING
A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES
WEST-NORTHWESTWARD AT 15 TO 20 MPH.

Oh I know that. It's just that some of us here are a little more "gunshy" than others.

Here's the 2004 track of Charley, Jeane, and Frances. My little town isn't marked on the map but it's midway between Lake Wales and Frostproof. Yep... We got our butts kicked 3 times in 6 weeks that year.
