...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF
SOUTHEASTERN FLORIDA ON THURSDAY AND FRIDAY, AS WELL AS THE
CENTRAL/SOUTHERN ROCKIES ON FRIDAY...
A FRONT WILL BE LINGERING OVER FLORIDA THROUGH SATURDAY. TROPICAL

EXCESSIVE RAINFALL OVER SOUTHEASTERN FLORIDA THROUGH FRIDAY

THE HEAVY RAIN WILL CONTINUE ON FRIDAY OVER FLORIDA. THEREFORE,
THE WPC HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL

FLASH FLOODING, WITH URBAN AREAS, ROADS, SMALL STREAMS, AND
LOW-LYING AREAS THE MOST VULNERABLE.
AN UPPER-LEVEL LOW OVER NORTHERN CALIFORNIA/GREAT BASIN WILL
PRODUCE LIGHT RAIN AND EMBEDDED THUNDERSTORMS OVER PARTS OF THE
NORTHWEST, NORTHERN CALIFORNIA, AND GREAT BASIN THROUGH THURSDAY
EVENING.
OVERNIGHT THURSDAY, MOISTURE WILL START TO STREAM NORTHWARD ACROSS
NORTHWESTERN MEXICO INTO THE SOUTHERN ROCKIES, PROVIDING PLENTY OF
FUEL FOR SHOWERS AND THUNDERSTORMS WITH HEAVY RAIN OVER PARTS OF
THE CENTRAL/SOUTHERN ROCKIES ON FRIDAY. THEREFORE, THE WPC HAS
ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER PARTS
OF THE CENTRAL/SOUTHERN ROCKIES 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.
BY FRIDAY, THE RAIN OVER CALIFORNIA AND MOST OF THE NORTHWEST WILL
END. HOWEVER, RAIN WILL CONTINUE OVER PARTS OF THE NORTHERN
INTERMOUNTAIN REGION, THE NORTHERN ROCKIES, AND THE NORTHERN
PLAINS THROUGH SATURDAY. LATE FRIDAY, UPPER-LEVEL ENERGY WILL
MOVE OVER THE GREAT LAKES, PRODUCING SHOWERS AND THUNDERSTORMS
OVERNIGHT FRIDAY INTO SATURDAY.
