NWS Issues Flood, Thunderstorm and Fire Weather Alerts Across U.S. States
National Weather Service alerts report active severe weather across multiple U.S. states Saturday, including flash flooding in Texas, ongoing river flooding in Iowa and Washington, severe thunderstorms in West Virginia, and critical fire weather in Alaska.
Texas Flash Flooding Underway
The National Weather Service in Fort Worth has issued a Flash Flood Warning for southwestern Fannin County in north central Texas and southeastern Grayson County in north central Texas until 3:30 PM CDT. [5] At 12:25 PM CDT, Doppler radar indicated thunderstorms producing heavy rain across the warned area. [5] Between 2 and 4 inches of rain have fallen with additional rainfall amounts of 1 to 2 inches possible in the warned area. [5] Flash flooding is ongoing or expected to begin shortly. [5] The warning covers areas where thunderstorms have already produced significant rainfall totals and where further accumulation could lead to rapid rises in water levels on roads and low-lying terrain. [5] Residents in the affected portions of Fannin and Grayson counties are advised to monitor conditions closely as the storms continue to move through the region. [5] The issued alert specifies that the combination of observed rainfall and expected additional amounts creates an immediate risk of flash flooding in these specific counties. [5]

A Flood Warning remains in effect for a portion of south central Iowa including the counties of Mahaska, Marion and Monroe until 9:00 PM CDT Saturday. [1] Flooding caused by excessive rainfall continues in these locations. [1] Flooding of rivers, creeks, streams, and other low-lying and flood-prone locations is imminent or occurring. [1] At 12:52 PM CDT, some roads remained closed due primarily to flooding along Cedar Creek. [1] Some locations that will experience flooding include areas along Cedar Creek where water levels have already impacted travel routes. [1] The warning highlights that excessive rainfall has led to ongoing inundation that affects both rural and low-lying spots across the three counties. [1] Continued monitoring is necessary as the flood conditions are expected to persist through the evening hours on Saturday. [1] The National Weather Service notes that the impacts extend to multiple waterways within the warned zone. [1]
Minor Flooding Forecast for Washington River
The Flood Warning continues for the Stehekin River at Stehekin affecting Chelan County in Washington. [3] Minor flooding is forecast for the Stehekin River at Stehekin until further notice. [3] At 20.5 feet, water inundates some properties and overtops the temporary corduroy bridge. [3] Company Creek Road is inundated at the northern end. [3] Battalion Creek culverts are beginning to experience impacts from the rising water. [3] The forecast indicates that these conditions will affect properties near the river and specific roadways in the Stehekin area. [3] The warning remains active without a set end time, reflecting the expectation that water levels will stay elevated for an extended period. [3] Impacts are described in detail for the 20.5-foot river stage, including inundation of certain access points and structures. [3]
Severe Thunderstorm Threatens West Virginia
At 1:45 PM EDT, a severe thunderstorm was located over Alum Creek, or 12 miles south of Nitro, moving east at 30 mph. [2] The hazard includes 60 mph wind gusts and quarter-size hail.

[4] Temperatures include highs in the mid to upper 70s and lows in the lower 50s. [4] Critical fire weather conditions are possible due to a combination of low relative humidity, gusty winds from the south, and dry conditions. [4] The warning covers both days of the weekend with the same timing window each day. [4] The forecast elements combine to create elevated fire danger across the Delta Junction area. [4]
