The National Weather Service (NWS) in Des Moines has issued a weather alert for this morning, warning that there is a Slight Risk (Level 2 of 5) for severe thunderstorms across parts of the region. A line of storms is currently tracking through the area, bringing the potential for localized damaging wind gusts and large hail.
Meteorologists at the National Weather Service in Des Moines emphasize that while the risk is localized, residents in the path of the storm system should remain alert for rapidly changing conditions. The primary hazards associated with this morning’s activity include strong, gusty winds and the possibility of small to medium-sized hail.
The Storm Prediction Center (SPC) categorizes a “Slight Risk” as an area where scattered severe thunderstorms are possible, which may be short-lived or not widespread. This level of risk is intended to help the public prepare for potential disruptions to outdoor activities and travel.

Understanding the severe thunderstorm risk
The current weather pattern indicates that the line of storms is moving across the state, with the NWS identifying the timing of these storms as a critical factor for morning commuters. According to the NOAA Storm Prediction Center, severe weather is defined by wind gusts of at least 58 mph, hail one inch in diameter or larger, or the presence of a tornado.
While the risk level for this morning remains at a 2 out of 5, the NWS advises that even non-severe thunderstorms can produce frequent lightning and heavy downpours, which may lead to temporary ponding on roadways. Drivers are encouraged to reduce speeds during heavy rainfall to avoid hydroplaning.
Safety measures for severe weather
When a severe thunderstorm warning or advisory is in effect, officials recommend moving indoors to a sturdy structure. The NWS highlights that the “when thunder roars, go indoors” mantra remains the safest course of action during any electrical storm.
| Risk Level | Description | Potential Impact |
|---|---|---|
| Level 1 (Marginal) | Isolated severe storms | Limited, localized damage |
| Level 2 (Slight) | Scattered severe storms | Damage to roofs, trees, or power lines possible |
For those caught outdoors, the NWS advises avoiding tall objects such as trees or metal poles. If you are in a vehicle, stay inside until the storm passes, as the metal frame provides a measure of protection, though it is not a substitute for a permanent building during extreme weather events.
What to watch for throughout the day
The situation remains fluid, and the NWS in Des Moines continues to monitor radar returns to track the development and intensity of the line of storms. Residents are urged to keep a battery-powered weather radio or a mobile device with emergency alerts enabled to receive the latest updates.
As the line of storms moves out of the immediate area later today, meteorologists will assess if the atmosphere remains primed for additional development in the afternoon or evening. Updates will be provided by the NWS as new data becomes available. For those planning outdoor events, checking the latest local forecast remains the most effective way to stay safe.
