Pocatello, ID – A widespread Flood Watch begins Saturday across eastern, southeastern and portions of central Idaho as a prolonged period of rainfall threatens to produce localized totals approaching 3 inches, raising concerns about flooded roads, rising creeks and low lying communities through Monday afternoon.
According to the National Weather Service in Pocatello, the Flood Watch takes effect at noon MDT Saturday, Oct. 10, and continues until 6 p.m. MDT Monday, Oct. 12.
The watch includes Idaho Falls, Pocatello, Rexburg, Blackfoot, Burley, Rupert, American Falls, Preston, Soda Springs, Driggs, Victor, Island Park and surrounding communities.
Portions of the Sun Valley region, including Ketchum, Hailey and Bellevue, are also included.
Forecasters expect widespread storm total rainfall amounts between 1 and 2 inches, with isolated locations potentially receiving closer to 3 inches.
An upper level low pressure system moving into the Pacific Northwest is expected to combine with tropical moisture, producing a cooler and wetter weather pattern across eastern Idaho.
Unlike brief thunderstorms, the extended duration of this rainfall event could allow runoff to accumulate over several days.
The National Weather Service warns that excessive runoff may cause rivers, creeks and streams to rise, increasing the potential for flooding in low lying and historically flood prone locations.
Communities throughout the Snake River Plain, Teton Valley and surrounding mountain regions should remain alert for changing water levels and localized flooding.
Motorists traveling across eastern Idaho should exercise caution near waterways, low water crossings and roads vulnerable to flooding.
Residents living near streams or drainage areas should monitor local conditions and prepare to respond if flooding develops.
A Flood Watch means flooding is possible, not necessarily occurring.
The National Weather Service encourages residents to follow updated forecasts and remain alert for possible Flood Warnings as the prolonged rainfall threat continues through Monday afternoon.
