Palmer police shut down the intersection of Colony Way and Glacier View Avenue after the road flooded. One car got caught in quick-moving water and ended up stuck in a hole in the shoulder after trying to turn around. The driver was safe and the car was towed.

Thunderstorms will continue to develop near Hatcher Pass and move south. Additional isolated thunderstorms are possible across the Mat-Su, in addition to Anchorage, Kenai and near Cooper Landing.
