SITUATION OVERVIEW
------------------
AT 8 AM, THE CENTER OF HURRICANE MILTON WAS LOCATED 75 MILES EAST
NORTHEAST OF CAPE CANAVERAL. MAXIMUM SUSTAINED WINDS WERE 85 MPH, AND
MOVEMENT WAS TOWARD THE EAST NORTHEAST AT 18 MPH.
MILTON IS FORECAST TO MAINTAIN HURRICANE STRENGTH THROUGH EARLY
AFTERNOON AS THE SYSTEM MOVES FARTHER OFFSHORE ACROSS THE ATLANTIC
WATERS BY THE LATE AFTERNOON HOURS. A TIGHT PRESSURE GRADIENT
ASSOCIATED WITH MILTON WILL CONTINUE STRONG WINDS ACROSS EAST CENTRAL
FLORIDA THIS MORNING. SOME DAMAGING WINDS GUSTS TO 65 TO 75 MPH MAY
OCCUR THIS MORNING ACROSS COASTAL AREAS, MAINLY NORTH OF SEBASTIAN
INLET.
HURRICANE WARNINGS REMAIN IN EFFECT FOR VOLUSIA AND BREVARD COUNTIES,
AND HURRICANE WARNINGS HAVE BEEN TRANSITIONED TO TROPICAL STORM
WARNINGS FOR LAKE, SEMINOLE, ORANGE, OSCEOLA, OKEECHOBEE, INDIAN RIVER
AND ST. LUCIE COUNTIES. A TROPICAL STORM WARNING ALSO REMAINS IN
EFFECT FOR MARTIN COUNTY. THE STRONG WINDS CONTINUING THIS MORNING
ACROSS EAST CENTRAL FLORIDA AND STRONG AND GUSTY WINDS ALONG THE
ATLANTIC COAST INTO THIS AFTERNOON WILL BRING CONTINUED POWER OUTAGES
TO SOME AREAS. JUST BECAUSE MILTON HAS SHIFTED OFFSHORE, DOESN'T MEAN
THE HAZARDS HAVE ENDED! IF POSSIBLE, AVOID VENTURING OUTSIDE.
A FLOOD WATCH REMAINS IN EFFECT FOR LAKE, SEMINOLE, ORANGE, VOLUSIA
AND NORTHERN BREVARD COUNTIES. ADDITIONAL RAINFALL AMOUNTS OF 1 TO
2 INCHES ARE POSSIBLE TODAY, MAINLY ACROSS VOLUSIA COUNTY AND NORTHERN
BREVARD COUNTIES. HOWEVER, NORTHERN PORTIONS OF EAST CENTRAL FLORIDA
RECEIVED VERY HEAVY RAINFALL FROM MILTON AND EXCESSIVE RUNOFF WILL
CONTINUE TO CAUSE FLOODING IN URBAN, LOW-LYING AND POOR DRAINAGE
AREAS. POINTS ALONG THE ST JOHNS RIVER AND THE LITTLE WEKIVA RIVER
ALSO REMAIN IN FLOOD STAGE.
THE SAINT JOHNS RIVER AT ASTOR WILL BE NEAR RECORD FLOOD LEVELS THIS
AFTERNOON AND INTO THE UPCOMING WEEKEND. ADDITIONAL LOCATIONS UPSTREAM
ON THE SAINT JOHNS ARE ALSO LIKELY TO EXPERIENCE RISES TO MODERATE TO
MAJOR FLOOD STAGE OVER THE NEXT SEVERAL DAYS.
A STORM SURGE WARNING IS IN EFFECT FOR ALL BREVARD BARRIER ISLANDS AND
COASTAL VOLUSIA COUNTY WHERE COASTAL FLOOD WATERS OF 3 TO 5 FEET ARE
POSSIBLE. SIGNIFICANT BEACH AND DUNE EROSION IS LIKELY. HEIGHTS UP TO
3 FEET WILL BE POSSIBLE ALONG THE TREASURE COAST. ADDITIONAL DUNE
EROSION IS POSSIBLE NEAR THE TIME OF THE NEXT HIGH TIDE BETWEEN 1 AND
3 PM THIS AFTERNOON. WATER LEVELS WILL CONTINUE TO BE ELEVATED ALONG
THE ATLANTIC COAST ON FRIDAY WITH MINOR COASTAL FLOODING POSSIBLE NEAR
THE TIMES OF HIGH TIDE.
DO NOT DRIVE INTO FLOODED ROADWAYS. BE ESPECIALLY CAREFUL NEAR DOWNED
TREES AND POWER LINES WHEN CLEANING UP FROM THE STORM.
