Bonk said that “very hot temperatures are contributing to an unstable atmosphere” and that “there is an unusually high amount of available moisture with the potential to produce hefty rain in an amount exceeding one inch in less than one hour.”

According to Bonk, thunderstorms are developing over the Cascades right now. The rain will be caused by the storms, which may persist even after the lighting and thunder have stopped. The watch is in effect from 3 to 10 p.m. on Monday for parts of southwest Washington and areas east of the Coast Range crest to the Cascades.
