Houston, TX — Halloween weekend plans across parts of the southern United States could face increasing uncertainty as federal forecasters identify an elevated risk of heavy precipitation across the Gulf Coast, Texas and portions of the Southwest beginning Friday, Oct. 30.
According to the NOAA Climate Prediction Center's outlook released Thursday, Oct. 22, several regions face a slight to moderate risk of heavy precipitation during the October 30 November 5 forecast period.
The most significant concerns include portions of Texas and the western Gulf Coast, where a moderate risk of heavy precipitation, representing a 40% 60% forecast probability, is highlighted from Friday, Oct. 30, through Sunday, Nov. 1.
That timeframe includes Halloween on Saturday, Oct. 31, raising the possibility of weather related disruptions to outdoor celebrations, trick or treating and community events.
Another moderate risk area is identified in the Southwest, primarily affecting portions of Arizona and New Mexico from Sunday, Nov. 1, through Monday, Nov. 2.
Surrounding regions, including additional portions of the Southwest, Southern Plains and lower Mississippi Valley, fall within broader slight risk areas, representing a 20% 40% probability of heavy precipitation during their designated forecast windows.
Areas to watch include:
Texas and western Gulf Coast: Moderate risk, October 30 November 1. Arizona and New Mexico: Moderate risk, November 1 2. Southern Plains and lower Mississippi Valley: Slight risk, October 31 November 2. Pacific Coast: Slight risk in portions of California, Oregon and Washington during the extended forecast period. The outlook does not guarantee rainfall at any specific location or indicate that Halloween activities will be washed out.
Instead, it identifies areas where the probability of unusually heavy precipitation is elevated during the forecast windows.
For families preparing outdoor Halloween activities, the timing makes upcoming forecast updates particularly important.
Residents in the highlighted regions should monitor local National Weather Service forecasts as Halloween approaches, especially if planning outdoor gatherings or traveling during potentially heavy rainfall.
