Persistant strong easterly winds caused coastal flooding in Hancock County.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
430 PM CST THU FEB 4 2010
.SYNOPSIS...
SURFACE LOW IS SITUATED OFF THE SOUTHWEST/SOUTH CENTRAL LOUISIANA
COAST WITH A SECONDARY LOW CLOSER TO THE UPPER SYSTEM OFF THE
LOWER TEXAS COAST. THE MID/UPPER TROUGH EXTENDS FROM THE CENTRAL
PLAINS SOUTH INTO WEST CENTRAL TEXAS AND MEXICO WITH THE CORE OF
THE STRONG UPPER LEVEL JET EXTENDING FROM THE WESTERN GULF COAST
NORTHWARD ACROSS THE EASTERN PLAINS TO THE GREAT LAKES. AREAS
RADAR SHOWED A LARGE SHIELD OF LIGHT TO MODERATE RAIN WITH
EMBEDDED AREAS OF HEAVY RAIN SHOWERS OVER MUCH OF THE CENTRAL GULF
COAST REGION.
&&
.SHORT TERM...
SURFACE LOW AND UPPER SYSTEM WILL SLOWLY ACCELERATE EAST AND
NORTHEAST TONIGHT. BANDS OF HEAVIER RAIN WILL PERSIST THIS
EVENING...MAINLY AROUND LAKE PONTCHARTRAIN AND AREAS TO THE EAST
AND SOUTH. LIGHT TO MODERATE RAIN OVER AREAS CLOSER TO THE
ATCHAFALAYA RIVER WILL START TO TAPER OFF LATER THIS EVENING AS
DRIER AIR NEAR THE SABINE RIVER WORKS EAST. WILL LEAVE THE FLOOD
WATCH INTACT OVER THE ENTIRE AREA...HOWEVER...ANTICIPATE THE
WESTERN HALF OR ONE THIRD OF THE WATCH AREA MAY BE CANCELLED LATER
THIS EVENING. RAINFALL TOTALS SO FAR HAVE BEEN FAIRLY CLOSE TO
WHAT WAS EXPECTED...WITH BATON ROUGE HAVING REPORTED JUST OVER 2.5
INCHES...METRO NEW ORLEANS AROUND 2 INCHES...AND GULFPORT AROUND 1
INCH. ADDITIONAL RAINFALL AMOUNTS WILL RANGE FROM AROUND ONE HALF
INCH AROUND KBTR TO 1 TO 2 INCHES AROUND METRO NEW ORLEANS...AND 2
TO 3 INCHES ON THE MISSISSIPPI GULF COAST. THERE HAVE BEEN REPORTS
OF HEAVY PONDING OF WATER ON LOW LYING SATURATED AREAS AND SOME
STREETS THAT HAVE EXPERIENCED NUMEROUS PERIODS OF HEAVY
RAINFALL...HOWEVER...NO FLASH FLOODING HAS BEEN REPORTED THUS FAR.
AFTER MIDNIGHT...RAIN WILL BE ENDING OVER THE WEST AND TAPERING
OFF IN THE EAST AS THE SURFACE LOW PRESSURE AREA MOVES EAST AND
NORTHEAST OF THE AREA.
ON FRIDAY...CLOUDS WILL HANG AROUND IN MOST AREAS. THE MAIN
SHORTWAVE TROUGH WILL MOVE FROM WEST TO EAST ACROSS THE FORECAST
AREA FOLLOWED BY A SECONDARY DISTURBANCE IN NORTHWEST FLOW FRIDAY
EVENING. ANY MEASURABLE RAIN CHANCES WILL BE CONFINED TO THE
MORNING OVER THE MISSISSIPPI GULF COAST AREA WITH SOME LINGERING
DRIZZLE POSSIBLE NORTH OF I-12 AND ACROSS SOUTHWEST MISSISSIPPI.
SOME DRIZZLE MAY PERSIST AROUND SOUTHWEST MISSISSIPPI DURING THE
AFTERNOON. MOSTLY CLOUDY SKIES WILL PERSIST FRIDAY NIGHT AS
SLIGHTLY COLDER AIR WORKS INTO THE AREA.
FOR THE START OF THE WEEKEND...SURFACE HIGH PRESSURE WILL BUILD
INTO THE FORECAST AREA SATURDAY...HOWEVER...LOW LEVEL MOISTURE
TRAPPED UNDER AN INVERSION WILL LIKELY KEEP BROKEN TO OVERCAST LOW
CLOUDS OVER AT LEAST THE NORTHERN HALF OF THE AREA. HAVE GONE
BELOW THE MAV GUIDANCE FOR HIGHS BASED ON THE FORECAST 925 AND 850
MB TEMPERATURES.
.LONG TERM...
A ZONAL FLOW PATTERN ALOFT BETWEEN SYSTEMS WILL BECOME ESTABLISHED
ON SUPERBOWL SUNDAY AS A RIDGE OF SURFACE HIGH PRESSURE MOVES
ACROSS THE LOWER MISSISSIPPI VALLEY. CLOUDS ARE EXPECTED TO BREAK
UP ALLOWING FOR PLENTY OF SUN WITH NO CHANCE OF RAIN. LOW
THICKNESS VALUES AND CONTINUED LOW 925-850 MB TEMPERATURES ONLY
SUPPORT HIGHS IN THE MID 50S.
THE NEXT WEATHER SYSTEM TO AFFECT OUR AREA WILL BE MOVING ACROSS
THE WESTERN STATES OVER THE WEEKEND THEN MERGING/PHASING WITH A
COLD UPPER SYSTEM DROPPING SOUTH OUT OF CENTRAL CANADA ON
MONDAY. THE GFS IS A BIT FASTER WITH THE SOUTHERN STREAM SYSTEM
AND SHOWS MUCH LESS PHASING THAN THE ECMWF. THE TIMING OF THE
ASSOCIATED COLD FRONT IS SIMILAR WITH THE TWO OPERATIONAL
MODELS...AND BOTH SHOW MOST OF THE FAST MOVING MODERATE TO HEAVY
RAINFALL PASSING NORTH OF THE FORECAST AREA...HOWEVER...THERE WILL
STILL BE A 40-50 PERCENT CHANCE OF LIGHT TO MODERATE SHOWERS
MONDAY NIGHT INTO TUESDAY MORNING.
COLDER AND DRIER AIR WILL SPREAD INTO THE GULF COAST REGION AGAIN
TUESDAY NIGHT AND WEDNESDAY WITH ANOTHER REINFORCEMENT POSSIBLE ON
THURSDAY. MODELS DIFFER QUITE A BIT ON THE AMOUNT OF COLD AIR
TOWARDS NEXT THURSDAY. WILL HAVE TO WATCH HOW THE MODELS HANDLE
THE NEXT DISTURBANCE LATE THURSDAY INTO FRIDAY SINCE COLD AIR
WILL BE IN PLACE. 22/TD
&&
.AVIATION...
A BROAD SHIELD OF LIGHT TO MODERATE RAINFALL WILL CONTINUE TO
IMPACT ALL TERMINALS THROUGH AROUND 03-06Z. MVFR VISIBILITIES AND
IFR CEILINGS WILL BE PREVALENT AT ALL TERMINALS...WITH CEILINGS
GENERALLY BETWEEN 500-1000 FEET AND VISIBILITIES OF AROUND 3
MILES. DRIER AIR WILL FILTER INTO THE MID-LEVELS AFTER 06Z...AND
STRONG EASTERLY WINDS OF 10 TO 15 KNOTS WILL TURN TO THE NORTH AND
NORTHWEST AFTER 06Z. HOWEVER...A LOW LEVEL INVERSION WILL TRAP
MOISTURE...WHICH WILL IN TURN ALLOW FOR IFR AND POSSIBLY LIFR
CEILING RESTRICTIONS TO CONTINUE THROUGH 16-18Z TOMORROW. 32
.MARINE...
SMALL CRAFT ADVISORIES REMAIN IN EFFECT FOR ALL OF OUR MARINE ZONES
THROUGH THIS EVENING. A BROAD AREA OF LOW PRESSURE IN THE NWRN GULF
WILL CONTINUE TO DEVELOP AND MOVE TO THE ENE TWRDS THE SE LA COAST.
THIS WILL KEEP WINDS ON THE HIGH END THROUGH THIS EVN BUT AS THE SFC
LOW MOVES THROUGH LOOK FOR ONSHORE FLOW TO BEGIN TO VEER AROUND TO
OFF SHORE AND TEMPORARILY WEAKEN DURING THE EARLY MORNING HRS. BY
MID TO LATE MORNING TOMORROW STRONG HIGH PRESSURE WILL BEGIN TO WORK
DOWN TWRDS THE NRN GULF AND THIS ALONG WITH CAA WILL CAUSE WINDS TO
PICK BACK UP WITH NW WINDS INCREASING THROUGH THE DAY AND MAXING OUT
OVERNIGHT. AHEAD OF THE SFC LOW ELEVATED TIDES WILL STILL BE AN
MINOR ISSUE BUT ONCE THE SFC LOW PUSH INTO SRN AL TOMORROW MORNING
TIDES WILL BEGIN TO DROP SOME. AS FOR SEAS THEY WILL RANGE IN THAT
5-7 FT RANGE THROUGH TONIGHT BUT BY TOMORROW AS OFFSHORE FLOW PICKS
UP AND ESPECIALLY TOMORROW NIGHT SEAS COULD APPROACH 9-10FT IN THE
OUTER WATERS. HIGH PRESSURE SHOULD FINALLY BUILD IN SATURDAY CAUSING
WINDS TO FINALLY SLACK OFF. BY THE BEGINNING OF NEXT WEEK ANOTHER
SFC LOW WILL BEGIN TO TAKE SHAPE IN TX AND THIS WILL LEAD TO AN
INCREASE IN BOTH WINDS AND SEAS AGAIN. /CAB/
