FLOOD WATCH DECLARED: Storm fueled by Tropical Cyclone Rachel could dump up to 3 inches of rain on East Idaho starting today
A storm loaded with tropical moisture is headed for East Idaho, with some areas expected to receive up to 3 inches of rain starting Saturday. That’s enough water that the National Weather Service has issued a flood watch from noon Saturday through Monday afternoon. The weather service said an upper-level low moving into the Pacific Northwest is teaming up with moisture from Tropical Cyclone Rachel to drive a prolonged stretch of cooler, wetter weather across East Idaho all weekend. The weather service previously said temperatures in East Idaho are expected to plunge, with overnight lows in the 30s and daytime highs in the 50s starting Saturday and continuing until Wednesday or Thursday. The cold and wet weather could also bring East Idaho’s higher elevations their first measurable snowfall of the season early next week. The weather service said it expects any snow accumulations to be light. But most of the precipitation is forecast to fall as 1 to 3 inches of rain across East Idaho. All that rain could send rivers, creeks and streams over their banks and flood low-lying areas, according to the weather service. The flood watch blankets all of East Idaho and some of south central Idaho,
