The southern storm corridor
A very strong El Niño often supports a jet stream displaced south and east. NOAA's October winter outlook therefore leans wet from the Southwest through the Gulf states and Southeast. The drought outlook also favors improvement across parts of the South and Southeast through January.
The temperature story is not the same everywhere. NOAA favors near-normal seasonal temperature for parts of the Southeast, including Florida. That category still allows brief cold spells and unusually warm weeks; it is a three-month average, not a daily temperature range.
What a wet tilt can mean locally
Repeated rain events can raise creek levels and saturate soils. A single intense system may produce flooding even if the season ultimately finishes near average. The outlook does not forecast particular flood dates, and drought improvement can coexist with damaging short-term runoff.
Some southern winter systems also include thunderstorms or a narrow wintry zone on their northern edge. The existence, location, and severity of those hazards depend on event-scale ingredients. Do not turn the seasonal El Niño signal into a claim of a specific tornado or ice-storm count.
What to do before a storm
Know which roads flood quickly and keep several ways to receive warnings. When a system approaches, consult local NWS flood, thunderstorm, and winter-weather forecasts together. For rain or ice amounts, the NWS probability portal gives a more useful range than the October seasonal map.
