...TROPICAL STORM DEBBY IS EXPECTED TO CAUSE POTENTIALLY
CATASTROPHIC FLASH AND URBAN FLOODING, LIFE-THREATENING STORM
SURGE, AND STRONG WINDS ACROSS PORTIONS OF NORTH FLORIDA AND THE
SOUTHEAST...
...THERE'S POTENTIAL FOR EXCESSIVE RAINFALL AND SEVERE
THUNDERSTORMS ACROSS PORTIONS OF THE UPPER MIDWEST, LOWER GREAT
LAKES AND NORTHEAST THROUGH TUESDAY...
...THERE ARE EXCESSIVE HEAT WARNINGS OVER PARTS OF
CENTRAL/SOUTHEASTERN CALIFORNIA AND THE SOUTHWEST AND HEAT
ADVISORIES OVER PARTS OF THE LOWER MISSISSIPPI VALLEY...
TROPICAL STORM DEBBY IS LOCATED OVER NORTH FLORIDA AS OF 3 P.M. ET
AND IS MOVING NNE AT 7MPH. TROPICAL STORM WARNINGS AND STORM SURGE
WARNINGS ARE IN EFFECT FOR NORTHWESTERN FLORIDA AND THE GEORGIA
AND SOUTH CAROLINA COASTLINES. IN TERMS OF SEVERE WEATHER IMPACT,
THE STORM PREDICTION CENTER ISSUED A SLIGHT RISK OF SEVERE
THUNDERSTORMS (LEVEL 2/5) FOR PORTIONS OF NORTHERN FLORIDA THROUGH
SOUTHERN/COASTAL GEORGIA AND INTO SOUTH CAROLINA'S CENTRAL COAST,
WHERE THE CHANCE FOR TORNADOES IS GREATEST. THE SEVERE WEATHER
THREAT WILL PERSIST INTO TUESDAY FOR THE POTENTIAL OF SPIN-UP
TORNADOES.
DEBBY IS LIKELY TO PRODUCE POTENTIALLY HISTORIC HEAVY RAINFALL
ACROSS NORTH FLORIDA AND SOUTHEAST GEORGIA AND SOUTH CAROLINA
THROUGH FRIDAY MORNING. SOUTHEAST GEORGIA AND THE CAROLINAS ARE
FORECAST TO RECEIVE 10-20 INCHES OF RAINFALL WITH ISOLATED MAXIMUM
VALUES OF 30 ". HEAVY RAIN WILL START TO CREEP NORTHWARD BY THE
MIDDLE OF THE WEEK FOR NORTH CAROLINA TO THE MID-ATLANTIC. ACTION
SHOULD BE TAKEN TO PREP FOR IMPACTS FROM HIGH WATER. TROPICAL
FORCE STORM WINDS MAY MAKE TRAVEL DIFFICULT FOR FIRST RESPONDERS
SO ACTION SHOULD BE TAKEN TO PROTECT LIFE AND PROPERTY BEFORE
INCLEMENT WEATHER CONDITIONS ARRIVE. FOR MORE INFORMATION GO TO
HURRICANES.GOV.
A SLOW MOVING COLD FRONT EXTENDING FROM THE NORTHERN HIGH PLAINS
TO THE NORTHEAST WILL BE THE FOCUS FOR SCATTERED SHOWERS AND
THUNDERSTORMS FOR THE REMAINDER OF MONDAY. HAIL AND DAMAGING WINDS
WILL BE THE BIGGEST THREAT. ADDITIONALLY, THE FRONT WILL SAG
SOUTHEAST TUESDAY AND PUT AREAS ALONG THE I95 CORRIDOR AND THE
MID-ATLANTIC UNDER THE RISK FOR FLASH FLOODING WHERE THUNDERSTORMS
TRAIN OVER THE SAME AREA; MORE THAN A COUPLE OF INCHES OF RAIN IN
A SHORT AMOUNT OF TIME COULD FALL. THERE IS A MODERATE RISK OF
EXCESSIVE RAINFALL IN EFFECT FOR SOUTHEAST PENNSYLVANIA AND NEW
JERSEY, AND THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL FOR
NORTHERN MARYLAND TO COASTAL NEW ENGLAND.
HIGH TEMPERATURES WILL LIKELY REMAIN WELL BELOW AVERAGE ACROSS THE
NORTHERN PLAINS AND UPPER MIDWEST OVER THE NEXT SEVERAL DAYS,
WHILE EXCESSIVE HEAT RISK GROWS ACROSS MUCH OF THE SOUTHERN TIER
OF THE U.S. FROM THE CENTRAL GULF COAST/LOWER MISSISSIPPI VALLEY
TO CALIFORNIA. EXCESSIVE HEAT WARNINGS ARE IN EFFECT ACROSS THE
DESERT SOUTHWEST AND PORTIONS OF CALIFORNIA'S SOUTHERN/CENTRAL
VALLEY THROUGH TUESDAY AS HIGHS REACH INTO THE LOW 110S. CENTRAL
TEXAS WILL SEE HIGHS IN THE 100S, WHILE THE GULF COAST HIGH
TEMPERATURES LOOK TO HOVER AROUND THE CENTURY MARK INTO THE MIDDLE
OF THE WEEK. HIGH DEWPOINTS WILL ALSO CONTRIBUTE TO HEAT STRESS.
STAY HYDRATED AND AVOID WORKING IN THE PEAK HEATING HOURS IF ABLE.
ELSEWHERE, MONSOONAL STORMS ARE LIKELY TO CONTINUE ACROSS THE
SOUTHWEST AND FOUR CORNERS REGION THIS WEEK WITH A SLIGHT RISK OF
EXCESSIVE RAINFALL OVER FAR SOUTH-CENTRAL ARIZONA ON TUESDAY.
