Drenching thunderstorms are forecast across eastern Gulf Coast states from Louisiana to Florida, while a large storm system is expected to bring heavy rain and flash flooding risk to the Southwest and Rockies. Saturday's national high reached 92 degrees at McAllen, TX, and the national low dropped to 17 degrees at Redmond, OR.

Why it matters

Flash flooding and travel delays are possible wherever the heaviest downpours persist, and the forecast covers a wide swath of the country at once. Residents across the United States should monitor local conditions as the system develops.

The national temperature extremes come from daily observations, with the 92-degree high at McAllen, TX and the 17-degree low at Redmond, OR recorded Saturday. Exact rainfall totals and the locations most at risk of flooding remain unspecified in the forecast.

The details

Thunderstorms are occurring across eastern portions of the Gulf Coast from eastern Louisiana to Florida, and showers extend north across the Mississippi River Valley into parts of the Midwest. Central Arizona, southern Utah and southwestern Colorado face increased flash flood risk, while dry weather is expected across the Great Plains and the Northeast.

Residents in the Gulf Coast states from Louisiana to Florida and in the Southwest should watch for flash flooding and plan for travel delays where heavy downpours occur. Keep updated on local forecasts and avoid driving through flooded roadways.

The takeaway

Heavy rain and flash flood risk can develop quickly across large areas, so checking the forecast before traveling helps reduce exposure to delays and hazards. Staying alert to local updates through the weekend is the most practical step for anyone in the affected regions.
