- The Southwest and Southeast face the heaviest downpours, with Level 1 and Level 2 flash‑flood risks, especially in Arizona and parts of the Deep South.

Fox Weather’s national outlook shows that rain will affect Halloween night in over 20 states, with the Southwest, Southeast and parts of the Midwest under the greatest threat of downpours and flash‑flood conditions.
In the Southwest, a potent storm system that slammed the region on Friday is expected to intensify on Halloween, bringing moderate‑to‑heavy rain to southern California, Utah, Arizona, western Colorado and western New Mexico. The forecast notes a Level 1 flash‑flood risk across the Southwest and a Level 2 threat centered on Central Arizona, including Phoenix. San Diego, which has recorded only nine measurable Halloween rain events since 1850 (the last in 1987), is also in the rain band.
Southwest and Southeast face heavy rain and flash‑flood threats
The Southeast and Gulf Coast are slated for heavy rain through the day, especially along the Mississippi Valley and the eastern Florida coastline. Portions of Alabama, Mississippi, West Tennessee and New Orleans could see significant rainfall, while Florida’s east coast is expected to remain wet into Sunday, with temperatures in the mid‑ to upper‑70s.
Midwest forecasts call for spotty showers in Missouri and Illinois, but overall temperatures will be unusually warm, running 10‑20 °F above average. Highs in the 70s and low 80s are expected, and Indianapolis could tie or break its record for the number of 70 °F days in October.
Midwest sees warm temperatures with spotty showers
The Northeast and Mid‑Atlantic are projected to have the most favorable Halloween weather, with dry conditions and mild daytime highs in the low‑to‑mid‑60s. Nighttime lows may dip into the 40s, creating comfortable trick‑or‑treating conditions, though a larger storm system is forecast to move into the area by Sunday, potentially bringing rain and gusty winds.
Authorities and residents are urged to monitor local forecasts, heed flash‑flood warnings where issued, and consider indoor alternatives if severe weather develops. Fox Weather will continue to update the outlook throughout the night.
