At 615 PM MDT, Doppler radar was tracking strong thunderstorms along
a line extending from 14 miles southwest of Lothair to 17 miles
northwest of The Knees. Movement was east at 30 mph.

Frequent lightning, torrential rainfall, pea size hail, and winds in
excess of 30 mph will be possible with these storms.

Locations impacted include…
Lothair, Tiber Dam and Galata.
If on or near Tiber Reservoir, get out of the water and move indoors
or inside a vehicle. Remember, lightning can strike out to 10 miles
from the parent thunderstorm. If you can hear thunder, you are close
enough to be struck by lightning. Move to safe shelter now! Do not
be caught on the water in a thunderstorm.

Persons in campgrounds should consider seeking sturdy shelter until
these storms pass.
