Don’t Wait: South Dakota’s Severe Storms Are About to Hit, Here’s What You Need to Know!

South Dakota is gearing up for severe thunderstorms that are expected to bring heavy rainfall, flash flooding, high winds, and hail over the next 24 hours. The National Weather Service has issued Severe Thunderstorm Warnings for several counties, including Sioux Falls, Rapid City, and Aberdeen, as the storm system intensifies and moves eastward. With damaging winds, flooding, and the possibility of property damage, residents are urged to take the necessary precautions.

Severe Thunderstorms Moving Across South Dakota

Starting this afternoon, severe thunderstorms are expected to impact the central and eastern parts of South Dakota, including Sioux Falls, Pierre, and Brookings. These storms will bring heavy rain, strong winds up to 65 mph, and frequent lightning. Areas like Sioux Falls and Mitchell will feel the brunt of the storm as it strengthens through the evening hours. If you are in the path of these storms, it’s crucial to stay indoors and seek shelter as the weather turns dangerous.

Flash Flooding a Major Concern

Heavy rainfall in a short amount of time will likely lead to flash flooding, particularly in low-lying areas and along rivers. Interstate 90, Interstate 29, and roads near the Missouri River could become submerged, creating hazardous driving conditions. Sioux Falls, Pierre, and Rapid City are among the areas at greatest risk for flooding. With these storms moving quickly, rivers and streams could overflow, and drainage systems may struggle to keep up with the downpour. Residents should avoid driving on flooded streets and stay alert to changing road conditions.

Strong Winds and Hail Could Cause Damage

In addition to heavy rain, strong winds and hail are expected to accompany the storms. Winds could gust up to 70 mph, which is enough to bring down trees and power lines, and cause structural damage. Hailstones up to 1 inch in diameter are possible, which could damage crops, vehicles, and roofs. Local authorities recommend securing any outdoor items like lawn furniture and trash cans and seeking shelter away from windows, trees, and large structures during the storm.

Power Outages and Travel Disruptions Likely

With the threat of high winds and flash flooding, power outages are a significant concern for South Dakotans. Sioux Falls, Rapid City, and Aberdeen could experience power disruptions, and residents should prepare for outages by charging devices, gathering flashlights, and having emergency supplies on hand. Travel disruptions are also expected, especially on flooded roads. Major highways like I-90 and I-29 could become impassable due to water and debris, so drivers should plan alternate routes.

What You Can Do to Stay Safe

As the storm approaches, take these precautions to protect yourself and your property:

1. Stay Indoors: Seek shelter as soon as the storm begins, especially during high winds and hail.

2. Monitor Weather Alerts: Keep track of updates from the National Weather Service for the latest warnings.

3. Avoid Flooded Roads: Do not drive through flooded areas, even if the water appears shallow. Turn around if you encounter a flooded roadway.

4. Prepare for Power Outages: Charge your phone, gather essentials like food and water, and keep a flashlight handy in case of a power loss.

South Dakota is bracing for a dangerous weather system that will bring severe thunderstorms, flash flooding, hail, and high winds. With the risk of property damage, flooded roads, and power outages, residents need to take immediate action to stay safe. By staying informed, securing outdoor items, and avoiding flooded roads, South Dakotans can help protect themselves and their property from this destructive storm system.
