NHC Flags Low Pressure Off Southeast Florida With 20% Chance of Tropical Formation

Forecasters say the system could boost rainfall and raise localized flood risk in Central Florida early next week.

Overview

  • The National Hurricane Center began monitoring the system on Saturday, June 27, and assigned a low 20% chance of tropical development over seven days.
  • Forecast models disagree on whether the disturbance will become a tropical cyclone but consistently show increased moisture over Central Florida with the heaviest rain expected Monday through Wednesday.
  • Some model runs project the feature drifting west into the northern Gulf and toward Louisiana later in the week, which would shift the primary impacts westward.
  • Weather agencies warn that heavy rain, pockets of gusty wind, rough seas, and localized flooding are the main near-term hazards whether or not the system becomes tropical.
  • Early-season frontal lows like this can form into low-end tropical systems fairly easily, and past weak coastal lows in the region have caused notable rain and flood problems even without full tropical development.
