...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF THE
WESTERN AND CENTRAL GULF COAST ON WEDNESDAY AND OVER THE SOUTHWEST
ON THURSDAY AND FRIDAY...
A FRONT EXTENDING FROM THE GREAT LAKES SOUTHWESTWARD TO WESTERN
TEXAS WILL MOVE TO THE NORTHEAST COAST, MID-ATLANTIC, AND THE
CENTRAL GULF COAST BY FRIDAY. MOISTURE FLOWING NORTHWARD FROM THE
GULF WILL POOL ALONG THE FRONT OVER THE WESTERN GULF COAST TO THE
OHIO/TENNESSEE VALLEYS, PRODUCING SHOWERS AND THUNDERSTORMS WITH
HEAVY RAIN OVER THE TWO REGIONS. THEREFORE, THE WPC HAS ISSUED A
SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER THE WESTERN
GULF COAST TO THE CENTRAL GULF COAST AND OVER THE OHIO/TENNESSEE
VALLEYS THROUGH THURSDAY MORNING. THE ASSOCIATED HEAVY RAIN WILL
CREATE MAINLY LOCALIZED AREAS OF FLASH FLOODING, WITH URBAN AREAS,
ROADS, SMALL STREAMS, AND LOW-LYING AREAS THE MOST VULNERABLE. ON
THURSDAY, SHOWERS AND THUNDERSTORMS WILL MOVE TO THE
MID-ATLANTIC/SOUTHEAST COAST, AS WELL AS THE CENTRAL GULF COAST.
ON FRIDAY, THE SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER THE
SOUTHERN MID-ATLANTIC AND SOUTHEAST.
MEANWHILE, AN UPPER-LEVEL LOW MOVING OVER SOUTHERN CALIFORNIA WILL
STREAM MOISTURE INTO THE SOUTHWEST ON THURSDAY, PRODUCING HEAVY
RAIN. THEREFORE, THE WPC HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF
EXCESSIVE RAINFALL OVER PARTS OF THE SOUTHWEST FROM THURSDAY
THROUGH FRIDAY MORNING. THE ASSOCIATED HEAVY RAIN WILL CREATE
MAINLY LOCALIZED AREAS OF FLASH FLOODING, WITH URBAN AREAS, ROADS,
SMALL STREAMS, AND LOW-LYING AREAS THE MOST VULNERABLE.
ON FRIDAY, THE UPPER LOW WILL CONTINUE TO STREAM MOISTURE INTO THE
SOUTHWEST, PRODUCING ANOTHER ROUND OF HEAVY RAIN. THEREFORE, THE
WPC HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL
OVER PARTS OF THE SOUTHWEST FROM FRIDAY THROUGH SATURDAY MORNING.
THE ASSOCIATED HEAVY RAIN WILL CREATE MAINLY LOCALIZED AREAS OF
FLASH FLOODING, WITH URBAN AREAS, ROADS, SMALL STREAMS, AND
LOW-LYING AREAS THE MOST VULNERABLE.
