FIRE WEATHER PLANNING FORECAST FOR EAST CENTRAL FLORIDA
NATIONAL WEATHER SERVICE MELBOURNE FL
300 PM EDT WED AUG 19 2026
..HEAT ADVISORY IN EFFECT UNTIL 8 PM EDT THIS EVENING
DISCUSSION
LIGHT WEST TO SOUTHWESTERLY FLOW PERSISTS ACROSS EAST CENTRAL
FLORIDA BETWEEN A QUASI-STATIONARY FRONT OVER THE SOUTHEAST US AND
HIGH PRESSURE IN THE ATLANTIC. DEVELOPMENT OF THE EAST COAST SEA
BREEZE WILL BE DELAYED/SLOWED BY THE OFFSHORE FLOW, LIKELY NOT
PUSHING INLAND OF THE COASTAL COUNTIES. WINDS SHIFT SOUTH TO
SOUTHEASTERLY WHERE THE SEA BREEZE CAN DEVELOP. RAIN AND STORM
CHANCES REMAIN NEAR TO ABOVE NORMAL (40-60%) IN HIGH MOISTURE.
CHANCES INCREASE THROUGH THE AFTERNOON, PEAKING IN THE EVENING ON
THE SEA BREEZE COLLISION, THEN DECREASING IN THE LATE EVENING OR
EARLY OVERNIGHT AS SHOWERS AND STORMS DISSIPATE OR PUSH OFFSHORE.
STORMS WILL BE CAPABLE OF LOCALLY GUSTY WINDS, FREQUENT LIGHTNING,
AND HEAVY RAINFALL. HEAT WILL REMAIN A CONCERN, AND WHILE GREATER
CLOUD COVER AND RAIN CHANCES BRINGS TEMPERATURES DOWN A FEW DEGREES
WITH HIGHS IN THE L-M90S, PEAK AFTERNOON HEAT INDICES REMAIN NEAR
HEAT ADVISORY CRITERIA IN THE U100-L110S. DISPERSION VALUES BECOME
MAINLY FAIR TO POOR DUE TO WEAK WINDS. NO MIN RH CONCERNS.
FOG POTENTIAL...WIDESPREAD FOG IS NOT FORECAST. LOCALIZED VISIBILITY
REDUCTIONS DUE TO SMOKE FROM NEW OR EXISTING FIRES WILL BE POSSIBLE
EVEN IF FOG IS NOT FORECAST.
