BOISE The National Weather Service has issued a Flash Flood Watch for much of Idaho, including the Treasure Valley, Boise and Owyhee mountains, Weiser area, Camas Prairie, Sawtooth and Salmon mountain ranges, the Big and Little Wood River valleys, and parts of the Magic Valley including Twin Falls.

Flash flood watches have been extended to much of eastern Oregon as well.

The watch extends from 11 a.m. Wednesday through Thursday afternoon.

Meteorologists say flash flooding in small creeks is possible, along with mudslides in areas recently burned by wildfire. Heavy rainfall is expected in areas with steep elevation.

A flash flood warning issued Tuesday for parts of Boise and Ada counties did not produce significant flooding. However, a strong line of thunderstorms that moved over parts of Idaho did leave more than 600 customers without power near the Boise Towne Square Mall.

Upwards of two inches of rain fell in some valley locations Tuesday. At least one small mudslide was reported near the Sun Valley area. See that story here.

KTVB Meteorologist Larry Gebert says flooding in mountain areas remains a safety issue. Those who live near streams, gulches, and dry creeks should monitor the rainfall and be ready to leave quickly if flood waters rise.
