A LATE SEASON HURRICANE MOVING NORTH FROM THE CARIBBEAN WILL
INTERACT WITH A BROAD AREA OF EASTERLY FLOW ACROSS THE GULF OF
MEXICO TO PRODUCE AN INCREASING THREAT OF HIGH WINDS...COASTAL
FLOODING AND HEAVY RAINS ALONG PORTIONS OF THE GULF COAST STATES
ON SUNDAY INTO TUESDAY.  

THE COMBINATION OF AN UPPER TROUGH OVER TEXAS...COMBINED WITH 
NORTHWARD MOVING HURRICANE IDA WILL YIELD A LARGE AREA OF HEAVY
RAINFALL THAT WILL SPREAD NORTHWARD ACROSS MUCH OF THE GULF.

INITIALLY...RAIN WILL DEVELOP ALONG COASTAL TEXAS AND LOUISIANA ON
SUNDAY...AND THEN SPREAD SLOWLY NORTHEASTWARD ON MONDAY TOWARD THE
SOUTHEAST UNITED STATES. SOME OF THIS RAINFALL WILL BE LOCALLY
HEAVY. WHERE AND HOW MUCH RAINFALL ON MONDAY INTO EARLY TUESDAY
WILL LIKELY DEPEND ON THE PATH OF THE HURRICANE. FOR MORE
INFORMATION ON HURRICANE IDA...SEE TPC UPDATES OR GO TO
WWW.NHC.NOAA.GOV.

ELSEWHERE AROUND THE COUNTRY...WARM WEATHER WILL CONTINUE FROM THE
SOUTH CENTRAL TO MUCH OF THE EASTERN UNITED STATES. A FRONTAL
BOUNDARY STRETCHING ACROSS THE CENTRAL PLAINS TO MIDWEST TO
NORTHEAST UNITED STATES WILL SEPARATE SOMEWHAT COOLER AIR FROM THE
WARM AIR.

A RELATIVELY WEAK AREA OF LOW PRESSURE ALONG THE FRONT ON SUNDAY
WILL MOVE EAST...NORTHEASTWARD TO THE UPPER GREAT LAKES BY EARLY
MONDAY ACCOMPANIED BY A FEW SHOWERS.  A COLD FRONT WILL SWING
EASTWARD BEHIND THE LOW AND WILL BE FOLLOWED BY A HIGH PRESSURE
SYSTEM THAT WILL BUILD INTO THE PLAINS AND NORTHERN MIDWEST BY
MONDAY INTO EARLY TUESDAY.  

AN AREA OF RAIN WILL LIKELY DEVELOP NEAR AND JUST BEHIND THIS
FRONT FROM THE SOUTHERN PLAINS EARLY ON MONDAY AND THEN DEVELOP
NORTHEASTWARD ACROSS SOME PARTS OF THE MIDWEST LATE MONDAY AND
EARLY TUESDAY. 

IN THE PACIFIC NORTHWEST...A STORM SYSTEM WILL MOVE NORTHEASTWARD
TOWARD SW CANADA BY MONDAY EVENING AND LOW PRESSURE WILL DEVELOP
ALONG ITS TRAILING COLD FRONT BY MONDAY EVENING. THE COLD FRONT
WILL CONTINUE EASTWARD ACROSS OREGON AND WASHINGTON LATE MONDAY
