Tallahassee, FL – Florida residents are being urged to prepare for potentially increased flooding during the upcoming winter season as the National Weather Service highlights how strong El Niño patterns can bring heavier rainfall, rising rivers and coastal flooding across the state.
According to the National Weather Service in Tallahassee, an educational update shared Thursday, Nov. 12, outlines three major flooding threats associated with strong El Niño winters: urban flash flooding, prolonged river flooding and coastal flooding.
The agency's seasonal precipitation outlook for December 2026 through February 2027 shows elevated probabilities of above normal rainfall across much of Florida.
Northern and central Florida are among the areas highlighted for increased rainfall potential, with portions of the state showing probabilities around 60% to 80% for above normal precipitation.
Forecasters explain that repeated heavy rainfall can rapidly saturate the ground, overwhelming drainage systems and producing flash flooding, particularly in urban communities.
River flooding presents another concern.
During strong El Niño winters, changes in the storm track can direct more frequent rainfall toward the Gulf Coast, increasing the possibility of prolonged flooding along Florida rivers.
The National Weather Service notes that some Florida river basins have experienced historically high water levels during previous El Niño winters.
River flooding can also persist into spring, with elevated water levels sometimes continuing through February, March and April.
Coastal communities face additional risks from strong low pressure systems that can push seawater inland, producing coastal flooding and beach erosion.
The agency says minor flooding risk around Apalachee Bay has historically been approximately 2.5 times higher during El Niño conditions.
Officials recommend clearing gutters and drainage systems, preparing sandbags where appropriate and reviewing flood insurance coverage before flooding develops.
National Flood Insurance Program policies generally carry a 30 day waiting period before coverage begins.
Drivers are also reminded never to enter flooded roadways, as many flood related deaths occur in vehicles.
The guidance describes seasonal risks associated with El Niño, not a current flood warning or a guarantee that flooding will occur.
