The primary risks include potential disruptions to outdoor Halloween plans due to rain and thunderstorms on Saturday. Coastal areas near Hancock County, Mississippi, may experience minor flooding, with water levels reaching less than a foot above normally dry ground. Boaters should exercise caution as rougher conditions are expected offshore, with high winds and elevated seas. Additionally, dry conditions earlier in the week have heightened fire risks, with low humidity and dry fuels creating favorable conditions for fire spread.
