The combination of a strong pressure gradient between a weak low pressure area over the western Bahamas and strong high pressure over the Northeast United States, along with deep moisture and instability east of an upper level low west of Naples, led to the formation of fast moving showers and thunderstorms which produced locally strong winds across Southeast Florida and the adjacent waters. Severe thunderstorms were observed over Southeast Miami-Dade County, and strong non-thunderstorm winds caused beach erosion in Palm Beach County.
