Heavy rain from Tropical Storm Priscilla has triggered flash flood warnings across parts of the U.S. Southwest, as weather officials caution residents to prepare for rapidly changing conditions. The storm’s moisture is expected to bring intense rainfall, raising concerns about urban flooding and dangerous road conditions.
The National Weather Service (NWS) warned of potential flash floods in Arizona, New Mexico, and parts of Texas, where rainfall could exceed normal limits within hours.
Meteorologists say the storm’s slow movement increases the risk of sudden, localized flooding in low-lying and desert regions.
Emergency agencies have been placed on alert, advising people to avoid driving through waterlogged roads and to follow evacuation orders if necessary.
Tropical Storm Priscilla formed earlier this week in the eastern Pacific, pushing bands of heavy rain inland. While the system has weakened, it continues to carry tropical moisture into the U.S., combining with existing weather systems to intensify showers.
Officials have urged travelers to monitor real-time weather alerts and prepare for delays caused by road closures or debris flows.
Flash flood watches remain active through Friday, especially near mountainous terrain and river valleys.
The storm’s remnants may continue to affect the region into the weekend, with forecasters warning of persistent wet conditions.
