At 1049 AM MDT, Doppler radar was tracking strong thunderstorms along a line extending from 12 miles northeast of Utah Test and Training Range North to 7 miles northwest of Knolls. Movement was northeast at 45 mph.
Hazard
Wind gusts up to 50 mph and half inch hail.

Impacts
Gusty winds could knock down tree limbs and blow around unsecured objects. Minor damage to outdoor objects is possible. Locations impacted include... Utah Test and Training Range North, Great Salt Lake North of the Causeway, Great Salt Lake South of the Causeway, Gunnison Island, Hat Island, and Lakeside. This storm will be capable of producing strong gusty winds on the Great Salt Lake. This will lead to a sudden increase in waves and very choppy waters which will result in hazardous boating conditions. Boaters are urged to seek safe harbor if possible. This includes Interstate 80 in Utah between mile markers 33 and 34.
Instructions
If outdoors, consider seeking shelter inside a building. Torrential rainfall is also occurring with these storms and may lead to localized flooding. Do not drive your vehicle through flooded roadways.
