RALEIGH, N.C. — A dangerous storm system is bearing down on millions of Americans across five states Monday afternoon, and forecasters are warning that the window to prepare is closing fast. Virginia, North Carolina, Washington DC, Baltimore, and northeast Colorado are all under an active severe weather threat — with very different but equally dangerous conditions expected on each end of the country.
Colorado: Giant Hail and Tornadoes This Afternoon
Residents across the High Plains of northeast Colorado need to stay weather-aware starting this afternoon. Isolated storms are expected to develop off the high terrain and quickly intensify. This particular storm mode is exactly the type that produces extremely large hail — the kind that can shatter windshields, damage roofs, and injure anyone caught outside. A tornado or two also cannot be ruled out as these storms feed off strong instability across the open Plains.
Virginia and North Carolina: Damaging Winds Rolling Off the Mountains
The larger threat Monday spans Virginia and North Carolina, where storms will tear off the mountains and accelerate toward the coast throughout the afternoon hours. Damaging straight-line winds are the primary concern with this setup. These winds can down trees, knock out power lines, and cause structural damage with very little warning. Residents from the Appalachian foothills to the coastal plain should have a plan in place before storms arrive.
DC and Baltimore: Quick Tornadoes Still on the Table
A warm front lingering across the Washington DC and Baltimore corridor is keeping the tornado threat alive for the metro area Monday. Forecasters flagged this zone the day before and say conditions have not improved. Quick-spin tornadoes near warm fronts are particularly dangerous because they can drop with almost no warning and touch down in heavily populated areas. Residents in both cities should keep a weather app active and know their shelter location.
Anyone in the affected areas should avoid being outdoors during peak storm hours, stay away from windows, and move to an interior room on the lowest floor of a sturdy building if a tornado warning is issued for their location.
