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

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

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
