Colaboradores
Iowa is facing a significant weather threat as severe thunderstorms and potential flash floods loom over a large portion of the state. The National Weather Service (NWS) has issued severe thunderstorm watches for nearly 40 counties in central, southern, and western Iowa, effective until 4 a.m. Friday. A flash flood watch is also in effect for roughly a third of the state, including Polk County, until 7 a.m. Friday.
The primary concern is the strong storms expected to move through the region this evening and overnight, particularly impacting western Iowa. These storms are anticipated to bring heavy rain and gusty winds, posing a threat to property and safety.
Severe Thunderstorm Warning Details
A severe thunderstorm warning was updated around 12:30 a.m., encompassing parts of Polk, Madison, Dallas, and Warren counties until 1:15 a.m. At that time, severe thunderstorms were located along a line extending from near Minburn to near Jordan Creek Town Center to near East Peru, moving east at 45 mph. The main hazards associated with these storms are 60 mph wind gusts, capable of damaging trees, roofs, and other property. Residents in these areas are strongly advised to seek shelter in an interior room on the lowest floor of a building.
Flash Flood Watch: What to Expect
The flash flood watch highlights the risk of excessive runoff leading to flooding of rivers, creeks, streams, and other low-lying and flood-prone areas. Rainfall amounts of one to three inches are likely, potentially leading to dangerous conditions. The NWS specifically mentions that the area between US 20 and IA 92 is at higher risk.
Safety Precautions
- Stay informed: Monitor local news and weather alerts for updates.
- Seek shelter: During severe thunderstorms, move to an interior room on the lowest floor of a sturdy building.
- Avoid flooded areas: Never drive or walk through floodwaters. Turn around, don't drown.
- Head to higher ground: If you are in an area prone to flash flooding, move to higher ground immediately.
The NWS warns that large hail, up to 2 inches in diameter, and wind gusts of 75 mph are possible. A few tornadoes could also develop. Residents are urged to take these warnings seriously and prepare accordingly.
