ORIGINAL STORY: Weather advisories in effect now for Utah

TUESDAY 8/17/21 11:47 p.m.

SALT LAKE CITY (ABC4) – A weather pattern shift is taking aim at Utah for our Tuesday and after a dry, hot, smokey run for the last two weeks in Northern Utah, changes are on the way.

A strong cold front is moving towards Utah with gusty winds ahead and behind it, strong storms as it arrives, heavy rainfall possible which could lead to flooding, and noticeably cooler temperatures behind it.

The changes are prompting weather conditions that warrant some warnings so here’s what’s in effect starting at noon:

Red Flag Warning: Fire danger has increased today. After a dry two-week period in much of the state, gusty winds, abundant lightning, and low relative humidity means critical fire conditions for West Desert, Wasatch, Central Mountains, and much of Northern and Central Utah. The warning holds until 9 p.m.

Flash flood watch: Our storms today have the potential to drop heavy rain and be slow movers. We are not strangers to flash flooding this summer, and the watch includes all areas prone to flooding like our National Parks. On top of including most of Central and Southern Utah, the watch expanded Tuesday morning to include the Uintas and the Wasatch Back. This watch holds until midnight. 

We also had the Storm Prediction Center upgrade our thunderstorm threat today in parts of the state. Much of Utah had a marginal risk for thunderstorms for Tuesday meaning heavy rain, hail, abundant lightning, and damaging winds are possible. The thunderstorm risk was upgraded to a slight risk for most of Central and West Central Utah. This means scattered severe storms are possible and the biggest impacts to areas under this risk are strong winds, heavy rain, and hail. The slight risk includes parts of Salt Lake County, Utah County, and areas around I-15 all the way to the I-70 corridor.

Remember, in order for a thunderstorm to be classified as severe, it needs winds equal to or exceeding 58 miles per hour and hail at or greater than 1” in diameter. 

Stay with the Pinpoint Weather Team as warnings evolve throughout the day.
