Strong Thunderstorms, Flooding, Heavy Rain For North Florida

JACKSONVILLE, Florida – The National Weather Service in Jacksonville is forecasting continued hot, humid, and unsettled summer-like conditions across Northeast Florida and Southeast Georgia through early next week.

Abundant tropical moisture, daily sea-breeze convergence, and warm temperatures will fuel afternoon and evening showers and thunderstorms across the region through at least early next week.

According to NWS Jacksonville, the probability of rainfall causing flash or urban flooding remains elevated today due to tropical moisture and the potential for training thunderstorms.

• Today (Saturday): Localized flooding concerns, particularly in urban areas, poor drainage spots, and along the I-95 corridor. Bouts of heavy rain possible with repeated thunderstorms.
• Sunday through early next week: Marginal Risk across much of Northeast Florida and Southeast Georgia, with locally higher probabilities where heavy downpours train or repeat.

According to NWS Jacksonville, summer-like conditions will dominate with daily afternoon and evening thunderstorms, elevated heat indices, and the potential for gusty winds in stronger storms.

Key hazards this period include:

• Daily afternoon/evening thunderstorms with locally heavy rainfall (1-3+ inches widespread, localized 4-6+ inches possible) and gusts up to 40-45 mph in stronger cells, especially near and north of I-10
• Urban and poor drainage flooding possible due to saturated ground and heavy downpours
• Heat indices of 95°–105°F inland (peak heat midday through early evening)
• Lightning safety critical – seek shelter in a building or hard-topped vehicle at the first sign of thunder or lightning

In its Saturday morning update, NWS Jacksonville highlighted warm and rainy conditions with thunderstorm chances mainly in the afternoon and evening. Isolated strong storms are possible near and north of I-10, capable of producing gusty winds.

Tropical moisture is expected to produce additional rainfall totals of widespread 1–3+ inches through early next week (localized higher amounts in training storms). While the rain benefits wildfire suppression, long-term drought persists and burn bans remain in effect for many counties.

With the ground saturated in many areas from recent heavy rain, even brief intense downpours this afternoon and evening could cause temporary urban and localized flooding. Motorists should exercise caution on slick roads.

Beachgoers should remain cautious of elevated surf and possible rip currents at Northeast Florida and Southeast Georgia beaches including St. Simons, Jekyll, Fernandina, Jacksonville, St. Augustine, and Flagler. Follow local beach patrol guidance.

North Florida and southeast Georgia locations expecting daily thunderstorms and elevated heat this period include: Gainesville, Ocala, Lake City, Starke, Palatka, Jacksonville (inland areas), Waycross, Brunswick, and Homerville.
