OUTLOOK AREA TODAY AND TONIGHT. WITH MODEST INSTABILITY...BUT
IMPRESSIVE WIND SHEAR IN PLACE...THE PRIMARY SEVERE WEATHER
HAZARDS ARE DAMAGING STRAIGHT LINE WINDS AND TORNADOES. LARGE HAIL
IS UNLIKELY DUE TO THE LIMITED INSTABILITY AND HIGH FREEZING LEVEL
HEIGHTS.

FLASH FLOOD WATCH...
A FLASH FLOOD WATCH IS IN EFFECT FOR ALL OF EAST TEXAS...AND
LOCATIONS IN LOUISIANA GENERALLY ALONG AND WEST OF A LINE FROM
ALEXANDRIA TO LAKE CHARLES. THROUGH FRIDAY NIGHT...MEAN AREAL
RAINFALL AMOUNTS OF 4 TO 6 INCHES ARE POSSIBLE OVER SOUTHEAST
TEXAS...WITH 3 TO 5 INCHES POSSIBLE OVER SOUTHWEST AND WEST
CENTRAL LOUISIANA. LOCALLY HIGHER AMOUNTS OF UP TO 7 INCHES ARE
POSSIBLE. WITH NEARLY SATURATED SOILS FROM PREVIOUS RAINS...RAPID
SURFACE RUNOFF IS EXPECTED.

LAKE WIND ADVISORY...
STRONG AND GUSTY SOUTHERLY WINDS ARE EXPECTED TO AFFECT THE AREA
TODAY INTO THIS EVENING. OVER SOUTHEAST TEXAS AND SOUTHWEST
LOUISIANA...SUSTAINED WINDS AROUND 20 MPH WITH GUSTS UP TO 40 MPH
WILL BE POSSIBLE. ELSEWHERE...SUSTAINED WINDS BETWEEN 15 AND 25
MPH...WITH GUSTS TO BETWEEN 30 AND 35 MPH WILL BE POSSIBLE.

SMALL CRAFT ADVISORY...
OVER THE GULF WATERS AND COASTAL LAKES AND BAYS...15 TO 25 KNOT
SOUTHERLY WINDS WILL RESULT IN WIND GENERATED WAVES UP TO 6 FEET
OUT TO 20 NM...AND UP TO 9 FEET OUT TO 60 NM.

COASTAL FLOOD ADVISORY...
BETWEEN SABINE PASS AND CAMERON...DURING TIMES OF HIGH TIDE
THURSDAY AFTERNOON...WATER LEVELS WILL BE BETWEEN 3.5 AND 4.0 FT
MLLW. IN JEFFERSON COUNTY...THIS WILL RESULT IN HIGHWAY 87 BETWEEN
SABINE PASS AND PORT ARTHUR HAVING SOME WATER ACROSS IT...AND
WAVES COULD PUSH DEBRIS ACROSS HIGHWAY 82 BETWEEN JOHNSON BAYOU
AND HOLLY BEACH IN CAMERON PARISH. FURTHER UP INTO CALCASIEU
PARISH...COMMUNITIES NEAR THE CALCASIEU RIVER SUCH AS DEATONVILLE

WILL CONTINUE TO BE STRONG AND GUSTY AHEAD OF THE FRONT ON
FRIDAY...PARTICULARLY OVER EAST CENTRAL AND SOUTH CENTRAL
LOUISIANA. THE THREAT OF SEVERE WEATHER WILL CONTINUE ALONG AND
AHEAD OF THE FRONT...WITH THE PRIMARY HAZARDS CONTINUING TO BE
DAMAGING WINDS AND TORNADOES. LOCALLY HEAVY RAINFALL WILL ALSO
CONTINUE TO BE A CONCERN...ESPECIALLY IN THE FLOOD WATCH AREA. AN
EXPANSION OF THE WATCH EASTWARD DOES NOT LOOK LIKELY AT THIS
TIME...AS RAINFALL AMOUNTS OVER EAST CENTRAL AND SOUTH CENTRAL
LOUISIANA DO NOT APPEAR SUFFICIENT TO CAUSE WIDESPREAD FLOODING.

PASSAGE OF THE FRONT WILL END THE COASTAL FLOOD WORRIES AND THE
SMALL CRAFT ADVISORIES FOR THE STRONG SOUTHERLY WINDS...THOUGH THE
NORTHERLY WINDS BEHIND THE FRONT MAY BE SUFFICIENT TO WARRANT AN
EXTENSION OF THE ADVISORY INTO FRIDAY NIGHT AND SATURDAY.

OTHERWISE...WEATHER SATURDAY THROUGH WEDNESDAY IS EXPECTED TO BE
BENIGN.
