TROPICAL STORM IDALIA IS FORECAST TO BRING HEAVY RAINFALL, STRONG
WINDS, SIGNIFICANT STORM SURGE, AND THUNDERSTORMS TO PARTS OF THE
FLORIDA GULF COAST BEGINNING TUESDAY NIGHT. PORTIONS OF THE WEST
COAST OF FLORIDA, THE FLORIDA PANHANDLE, SOUTHEAST GEORGIA AND THE
EASTERN CAROLINAS COULD RECEIVE 4-8 INCHES OF RAINFALL BY
THURSDAY. ISOLATED HIGHER TOTALS OF 12 INCHES ARE POSSIBLE,
PRIMARILY NEAR LANDFALL IN NORTHERN FLORIDA. A MODERATE RISK OF
EXCESSIVE RAINFALL LEADING TO FLASH FLOODING IS IN EFFECT FOR THIS
PART OF NORTHERN FLORIDA ON TUESDAY. AREAS OF TROPICAL STORM
WATCHES AND WARNINGS, AND HURRICANE WATCHES ARE IN EFFECT ACROSS
MUCH OF THE FLORIDA GULF COAST. FOR MORE INFORMATION ON IDALIA GO
TO HURRICANES.GOV.
A QUASI-STATIONARY FRONT, CURRENTLY DRAPED ACROSS THE LEE OF THE
SOUTHERN APPALACHIANS DOWN THROUGH THE CENTRAL GULF COAST WILL BE
THE FOCUS FOR ROUNDS OF AFTERNOON/EVENING CONVECTION TODAY. A
BROAD SLIGHT RISK AREA IS IN EFFECT FROM SOUTHERN VIRGINIA TO
NORTHEASTERN ALABAMA, WHERE CONVECTION ENHANCED BY UPSLOPE FLOW
OVER THE SOUTHERN APPALACHIANS COULD POSE FLASH FLOODING CONCERNS
WITH RAINFALL RATES BETWEEN 1-2IN/HR.
A PERSISTENT RIDGE IN THE SOUTHWEST WILL CONTRIBUTE TO ANOMALOUSLY
WARM TEMPERATURES
