Severe thunderstorms in the Spokane area and to the east of Coeur d’Alene were moving quickly to the north after sweeping across the area shortly after 4 p.m.
The storms were part of a broader swath of severe storms that extended from southeast Washington into the fire zones of Central Washington and northward toward the Canadian border.

A long line of storms formed north of Spokane and continued and continued across a broad swath on a fast track into Canada.
“I thought we were in a tornado,” said Krystle Schneider, who lives in a Northwest Spokane neighborhood hit hard by the storm.
Homes across the street and next door to Schneider’s home on Crown Avenue near Assembly were struck by large trees. Several large pine trees on her block toppled and blocked the street.

Avista Corp initially reported that 8,800 customers were without power in north Spokane, Colville and the Palouse.
That number quickly swelled to 16,000 customers without power as the storm went north and then to 18,600 just before 5 p.m. and then nearly 20,000 a short time later. By 5:40 p.m, the outage count stood at almost 22,000 and then 26,000 at 5:50 p.m.

Earlier in the day, the weather service posted a severe thunderstorm warning for an area from southeast Washington northward to Pullman and portions of the Palouse through 3:30 p.m.
Pullman saw hail the size of Ping-Pong balls, the weather service reported.
As the thunderstorms migrated northward, they were forecasted to strike in a large area of Eastern Washington and North Idaho. The forecast turned out to be correct.
Forecaster Ron Miller at the weather service said the Inland Northwest sees strong thunderstorms similar to the ones today about once every seven years. However, the last strong thunderstorm here was in 2012.
The storms were aided by warm sunny weather this morning, just ahead of an advancing low pressure area off the Pacific Ocean.
The warmth carried plenty of moisture in the air. When the low pressure area arrived during peak daytime heating in the afternoon, it sent the warm air skyward allowing it to generate the damaging storms.
“This one was pretty much perfect timing,” Miller said.
In Central Washington, flash floods from heavy thunderstorms are being reported along the Entiat River in the vicinity of one of the Central Washington fire scars.
Two flash flood warnings were issued this afternoon for mountain an area northeast of Wenatchee and second area near Winthrop in the vicinity of the Carlton Complex fires in Okanogan County.
One flash flood brought down debris at mile 11 at the Entiat River and boulders were dislodged during a storm near Tommy Creek earlier today, the weather service said.
Flash flooding was reported in the burned over area at the Carlton Complex. In addition, hail the size of quarters was reported.
The Central Washington flash flood warnings remain in effect until 7:15 p.m.
