...HEAVY RAIN TO IMPACT THE GULF COAST AND SOUTHEAST...


SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE GULF COAST STATES
AND THE SOUTHEAST U.S. OVER THE NEXT FEW DAYS. A SURFACE LOW
LOCATED IN THE WESTERN GULF REGION WILL GLIDE EASTWARD TOWARD THE
FLORIDA PANHANDLE ON TUESDAY. MOST OF THE HEAVIER RAIN WILL
CONCENTRATE ALONG THE COAST FROM LOUISIANA TO THE EMERALD COAST OF
FLORIDA.  IN ADDITION, SCATTERED SHOWERS AND THUNDERSTORMS WILL
OCCUR IN PARTS OF SOUTHEAST AND NORTHERN TEXAS AND OKLAHOMA.  THIS
AREA OF PRECIPITATION WILL MOVE EASTWARD INTO THE LOWER
MISSISSIPPI VALLEY BY TUESDAY EVENING, WITH MOST OF THE RAINFALL
BEGINNING TO TAPER OFF ACROSS THE SOUTHERN PLAINS REGION. BY
TUESDAY NIGHT, THE SURFACE LOW NEAR THE COAST WILL MOVE ACROSS
NORTHERN FLORIDA.  ALTHOUGH THE PRECIPITATION WON`T BE NEARLY AS
HEAVY AS IT WAS, SHOWERS AND THUNDERSTORMS WILL LINGER ACROSS
NORTHERN FLORIDA. EVENTUALLY, BY WEDNESDAY AFTERNOON, THIS LOW
PRESSURE SYSTEM WILL MAKE ITS WAY INTO THE ATLANTIC AND TAKE A
NORTHERLY TRACK ALONG THE EAST COAST. CONSEQUENTLY, MOST OF THE
SHOWERS AND THUNDERSTORMS WILL CONCENTRATE IN THE SOUTHEAST WITH
THE BULK OF THE ACTIVITY FOCUSING AROUND THE CAROLINAS.

THE PACIFIC NORTHWEST WILL HAVE NUMEROUS ROUNDS OF SHOWERS
THROUGHOUT THE SHORT TERM PERIOD.  LIGHT SHOWERS WILL BEGIN TO
MOVE ONSHORE IN RESPONSE TO A COLD FRONT APPROACHING THE COAST.
THIS LIGHT TO MODERATE ACTIVITY WILL CONTINUE THROUGHOUT THE DAY
ON TUESDAY AND INTO WEDNESDAY.
