UPDATED APRIL 4 AT 9:23 A.M. - There is an enhanced risk of severe thunderstorms this evening between 9-11 p.m. All modes of severe weather are possible with high winds and large hail being the primary threat. There is a low chance for tornadoes. Discrete cells may move across the area around 9-10 p.m., and the main front should pass through at 10-11 p.m. Storm activity should be through the area by midnight.
Remember, sirens aren’t just for tornadoes!
Allen operates 26 outdoor warning sirens that sound during severe weather events, including:
- Large hail greater than 1 inch in diameter
- Winds greater than 70 mph
- Tornado warnings naming Allen in the path
Allen uses data from the National Weather Service, weather radars, and trained storm spotters/public safety officers to determine when these criteria are met. Please do not rely on outdoor warning sirens, as the sound may not adequately penetrate a home to awake sleeping residents. Allen Emergency Management recommends using at least two methods of weather alerting to stay aware, which should include an NOAA weather radio. Learn more about storm and tornado safety.
