From the National Weather Service: Thunderstorms are expected to increase across parts of North Texas on Monday, Jan. 2 as a storm system moves through the Plains. Scattered showers and a few storms will develop around midday, but will increase in coverage through the afternoon, particularly east of I-35. Some storms during the afternoon will be severe and capable of producing damaging winds, tornadoes, and some hail.
Allen operates 26 outdoor warning sirens that sound during severe weather events, including large hail, heavy winds and tornado warnings. Though the sirens are placed strategically throughout the city, they are designed to warn people who are outdoors. People who are inside may not hear them, as air conditioning, thunder, wind, rain and other conditions can drown out the sound. Sirens are activated for:
- Hail greater than 1 inch in size
- Winds greater than 70 mph
- Tornado warnings from the National Weather Service naming Allen in the path
If you hear sirens, you should get indoors, find shelter and seek information. The best source for weather warnings is an NOAA all-hazards weather radio which activates when it receives a radio signal from the NWS. You can put the radio near your bed to wake you up if you’re asleep, and there’s adaptive technology available for people with vision or hearing impairments. View NOAA radio frequencies.
