Colorado’s Active Severe Weather Pattern
Colorado has experienced an active summer thunderstorm season, with repeated outbreaks of severe weather across the Front Range and eastern plains. Warm, unstable air combined with increasing moisture has supported numerous episodes of hail, damaging winds, and isolated tornadoes in recent weeks. Forecasters expect this pattern to continue whenever sufficient daytime heating combines with approaching weather disturbances.
Safety Tips During a Severe Thunderstorm
If a warning has been issued:
- Move indoors immediately.
- Stay away from windows and glass doors.
- Avoid using corded electrical devices during lightning.
- Delay travel until storms have passed.
- Secure outdoor furniture and loose objects.
- Never drive through flooded roadways.
- Keep multiple ways to receive emergency weather alerts.
Stay Weather Aware
Severe thunderstorms can intensify quickly across the Denver metro area and northeastern Colorado. Continue monitoring forecasts, local emergency management agencies, and National Weather Service updates until the warning expires or conditions improve.
Being prepared and acting quickly can help protect your family and property during rapidly changing weather conditions.
