Severe storms can produce large hail, damaging wind, lightning, and flash flooding.

Flooding can happen fast and often impacts roads before people expect it.
Lightning can strike before heavy rain reaches your location.
Heat illness can develop quickly, especially for older adults, children, and outdoor workers.
Snow, ice, and wind chill can create dangerous travel and exposure conditions.
Dry fuels, wind, and low humidity can spread fire rapidly.
Rip currents can pull swimmers away from shore quickly.
Hurricanes bring wind, surge, inland flooding, and long-duration impacts.
A watch means severe weather is possible. A warning means severe weather is happening or expected very soon.
In simple terms: large hail, very strong wind, or tornado potential from thunderstorms.
Even moderate-looking percentages can signal meaningful risk compared to a normal day at one location.
Marginal to High means increasing organized severe storm threat. Higher levels need more planning and faster response.
Watch means possible. Warning means act now. Advisory means caution for lower-level but impactful weather.
Severe criteria include large hail, damaging wind, or tornado potential within thunderstorms.
