...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF THE
WESTERN GULF COAST ON MONDAY, EXPANDING INTO THE CENTRAL GULF
COAST BY TUESDAY...
...DANGEROUS HEAT CONTINUES TO IMPACT PORTIONS OF SOUTHERN
CALIFORNIA AND THE SOUTHWEST THROUGH MONDAY...
...THERE ARE EXCESSIVE HEAT WARNINGS AND HEAT ADVISORIES OVER
PARTS OF SOUTHERN CALIFORNIA AND THE SOUTHWEST...
A QUASI-STATIONARY FRONT WILL LINGER ALONG THE GULF COAST THROUGH
TUESDAY. TROPICAL MOISTURE POOLING ALONG THE BOUNDARY WILL ALSO
CREATE SHOWERS AND THUNDERSTORMS THROUGH TUESDAY. ON MONDAY, THE
SHOWERS AND THUNDERSTORMS WILL PRODUCE HEAVY RAIN OVER PARTS OF
THE SOUTHERN TEXAS COAST. THEREFORE, THE WPC HAS ISSUED A SLIGHT
RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER PARTS OF THE WESTERN
GULF COAST FROM MONDAY INTO TUESDAY 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.
MOREOVER, ON TUESDAY, THE SHOWERS AND THUNDERSTORMS WITH HEAVY
RAIN WILL EXPAND ALONG THE WESTERN GULF COAST INTO THE CENTRAL
GULF COAST. THEREFORE, THE WPC HAS ISSUED A SLIGHT RISK (LEVEL
2/4) OF EXCESSIVE RAINFALL OVER PARTS OF THE WESTERN AND CENTRAL
GULF COAST ON TUESDAY. 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.
MEANWHILE, WEAK MONSOONAL MOISTURE WILL AID IN PRODUCING SHOWERS
AND THUNDERSTORMS OVER PARTS OF THE GREAT BASIN AND
CENTRAL/SOUTHERN ROCKIES FROM THE LATE AFTERNOON INTO THE LATE
EVENING ON SUNDAY AND MONDAY. IN ADDITION, WEAK UPPER-LEVEL ENERGY
OVER THE NORTHERN INTERMOUNTAIN REGION WILL PRODUCE SCATTERED
SHOWERS AND THUNDERSTORMS OVERNIGHT SUNDAY AND OVER PARTS OF THE
NORTHERN PLAINS/UPPER MISSISSIPPI VALLEY OVERNIGHT MONDAY INTO
TUESDAY.
ADDITIONALLY, UPPER-LEVEL RIDGING OVER THE PARTS OF SOUTHERN
CALIFORNIA AND THE SOUTHWEST PLAINS WILL ALLOW HIGH TEMPERATURES
TO BE IN THE UPPER 90S AND LOW 100S, PROMPTING EXCESSIVE HEAT
WARNINGS AND ADVISORIES OVER PARTS OF THE REGION. ADDITIONALLY,
WITH LOW TEMPERATURES IN THE LOWER 80S AND UPPER 70S, LITTLE
RELIEF FROM THE HEAT WILL OCCUR OVERNIGHT. THEREFORE, PEOPLE
SPENDING MORE TIME OUTDOORS OR IN A BUILDING WITHOUT COOLING IN
AREAS WITH HEAT WARNINGS ARE STILL AT AN INCREASED RISK OF
HEAT-RELATED ILLNESS.
