THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHEAST
LOUISIANA...SOUTH MISSISSIPPI AND THE ADJACENT COASTAL WATERS.

.DAY ONE...TODAY AND TONIGHT

A VIGOROUS STORM SYSTEM WILL BRING A MULTITUDE OF IMPACTS TO THE
REGION THIS WEEKEND. SEVERE WEATHER...HEAVY RAIN...COASTAL
FLOODING...AND MARINE ISSUES ARE ALL HIGHLIGHTED.

THE MAIN CONCERN WITH THIS SYSTEM WILL BE THE THREAT OF STRONG
AND SEVERE THUNDERSTORMS. THE STORM PREDICTION CENTER HAS PLACED
MOST OF THE OUTLOOK AREA UNDER AN ENHANCED RISK FOR SEVERE
WEATHER. THE MAIN TIME FRAME WILL BE TONIGHT AND THROUGH SUNDAY
MORNING WITH SEVERE WEATHER POSSIBLE ACROSS THE ENTIRE REGION BUT
THE AREA WITH THE GREATEST THREAT FOR SEVERE STORMS WILL BE ALONG
AND EAST OF A LINE FROM NEAR BATON ROUGE TO NEAR MCCOMB. ALL MODES
OF SEVERE WEATHER WILL BE POSSIBLE...HOWEVER THE MAIN THREATS WILL
BE DAMAGING THUNDERSTORM WINDS AND ISOLATED TORNADOES.

IN ADDITION TO THE SEVERE THREAT HEAVY RAINFALL COULD BECOME AN
ISSUE TOO. MULTIPLE ROUNDS OF MODERATE TO HEAVY RAIN COULD
DEVELOP WITH THE FIRST BATCH OF RAIN POSSIBLE SATURDAY AFTERNOON
AND EVENING WITH THE WARM FRONT MOVING NORTH. WIDESPREAD 2 TO 3
INCHES OF RAIN ARE ANTICIPATED WITH LOCALLY HIGHER AMOUNTS
POSSIBLE THROUGH THE WEEKEND.

AS THIS SYSTEM CONTINUES TO DEVELOP AND MOVE INTO THE MID AND
LOWER MISSISSIPPI VALLEY WINDS WILL INCREASE OVER THE COASTAL
WATERS. SMALL CRAFT ADVISORIES ARE IN EFFECT FOR ALL OF THE
COASTAL WATERS. STRONG EAST WINDS NEAR 20 KNOTS WITH GUSTS UP TO
30 KNOTS ALONG WITH ROUGH SEAS CAN BE EXPECTED.

LAST BUT NOT LEAST...THE STRONG ONSHORE EASTERLY FLOW WILL PRODUCE
HIGHER THAN NORMAL TIDES AND A POTENTIAL COASTAL FLOOD THREAT
FROM THIS AFTERNOON THROUGH EARLY SUNDAY MORNING. A COASTAL
FLOOD ADVISORY IS IN EFFECT FOR THIS TIME PERIOD FOR THE EAST
FACING SHORES FROM BAY ST LOUIS MISSISSIPPI TO THE MOUTH OF THE
MISSISSIPPI RIVER...INCLUDING LAKE BORGNE... THE RIGOLETS AND CHEF
MENTEUR PASS. TIDES ARE EXPECTED TO BE 1 TO 2 FEET ABOVE NORMAL
WHICH MAY RESULT IN MINOR FLOODING OF ACCESS AREAS NEAR THE COAST
OUTSIDE THE HURRICANE LEVEE PROTECTION SYSTEM.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THE STRONG WINDS WILL CONTINUE OVER THE COASTAL WATERS THROUGH THE
REST OF THE WEEKEND WITH SMALL CRAFT ADVISORY CONDITIONS EXPECTED
OVER ALL OF THE COASTAL WATERS...INCLUDING THE SOUNDS AND TIDAL
LAKES. WINDS MAY TEMPORARILY SLACK OFF SUNDAY NIGHT BUT AS A COLD
FRONT MOVES THROUGH MONDAY AND WINDS VEER AROUND TO THE NORTHWEST
THEY WILL LIKELY PICK BACK UP TO AROUND 20 KNOTS WITH HIGHER
GUSTS.

.SPOTTER INFORMATION STATEMENT...

THE ACTIVATION OF STORM SPOTTERS...AND EMERGENCY MANAGEMENT
PERSONNEL IN SUPPORT OF SEVERE WEATHER OPERATIONS MAY BE NEEDED
FOR PORTIONS OF THE REGION SATURDAY NIGHT THROUGH SUNDAY MORNING.
OZONE AMATEUR RADIO CLUB...W5SLA...WILL BE ACTIVATED SATURDAY
EVENING THROUGH SUNDAY MORNING.
