BOISE -- Isolated thunderstorms, high winds, and reports of lightning strikes created a hassle for many throughout southwest Idaho Tuesday.


The line of storms began moving through the Treasure Valley late Monday night, followed by wind speeds of up to 35 mph late Tuesday morning.

A flash flood watch was issued on Tuesday for areas scarred by forest fires in parts of Boise, Elmore, and Valley counties until 1:15 p.m. The warning expired without incident.

The watch is particularly concerning for those traveling in Valley County on Highway 55 near the Banks-Lowman-Smith's Ferry area where mudslides and rock falls are a danger. Officials say mud and rock slides can happen hours after a heavy rain.

The National Weather Service issued a severe thunderstorm warning for Boise, Elmore, Gooding, and Twin Falls counties at 11:30 a.m. The warning included storm winds capable of blowing over 60 mph.


Tuesday's rain showers and high winds caused periodic power outages throughout the Treasure Valley.

Idaho Power media representative Brad Bowlin told KTVB that 4,000 customers were without power shortly after 1 p.m. Tuesday.

Half of those customers were reported in a section of downtown Boise near State Street and the Boise River.

The other half stretched from Boise to Idaho City down the Highway 21 corridor. Communities experiencing power outages included Wilderness Ranch,RobieCreek, Star Ranch, Placerville, and Centerville.

A separate power outage affecting over 2,400 customers was reported shortly after 5 a.m. Tuesday in Nampa.

That outage affected customers in Nampa for approximately four hours, and Idaho Power says that particular outage was caused by a downed power line.

As of 2:30 p.m. there were more than 400 customers in the Grandview-Oreana area that still did not have power. Idaho Power says the outages are storm-related and they are working to fix the problem.

At 8:00 p.m. there were around 1,000 customers without power in the Jordan Valley area near the Idaho-Oregon border. A spokesperson says crews are on scene but they are having a hard time keep the lights on. Customers may notice some flickering and then the lights go out again. No estimate of when the problem will be completely fixed.

Idaho Power is reporting thousands are without power in Jerome, Twin Falls, and Minidoka Counties. Jerome, Twin Falls, Wendell, Hagerman, Rupert, Paul, Heyburn, Burley, Hansen, Murtaugh, Buhl, Bellevue, and Filer have all been affected. Idaho Power has crews out working on these outages and has no estimated time of restoral.
