8/17/2026, 6:36:39 AM
Core Event
The National Weather Service (NWS) issued a severe weather outlook covering the Baltimore region from Sunday night through Monday. The outlook warns of thunderstorms, wind gusts up to 50 mph in the city (up to 70 mph near the Chesapeake Bay), heavy rainfall on already saturated soils, and the possibility of an isolated tornado. The alert, which began at 5 p.m., is expected to expire by 11 p.m.
Expected Hazards
- Wind: Gusts of up to 50 mph in Baltimore and 70 mph closer to the Bay could down trees and power lines.
- Rainfall: The NWS forecasts “heavy, intense rainfall” that may cause flash flooding, especially in urban areas with poor drainage.
- Tornado Potential: While an isolated tornado or two is deemed possible, officials stress that gusty winds and flash flooding pose the greatest danger.
- Temperature & Visibility: Low temperatures will remain in the low 70s, with near-100 % chance of rain and reduced visibility after sunset.
Official Outlook Summary
The NWS describes the approaching strong frontal system as the driver of deteriorating conditions, noting that it will pass through the greater Baltimore/Washington region by evening. The service highlights that the combination of saturated ground, intense rain, and strong easterly winds creates heightened risk for flooding of small streams, creeks, and urban drainage networks.
Impact on the Community
Residents in neighborhoods with limited drainage are advised to prepare for rapid water accumulation and possible power outages. Emergency managers emphasize the importance of securing loose objects, avoiding travel during the peak wind period, and staying informed through local alerts. The outlook improves after midnight, with winds expected to subside and clearer skies returning for the start of the workweek.
Short-Term Forecast Outlook
- Monday: Mostly sunny with highs in the upper 80s and a 30 % chance of afternoon showers.
- Tuesday–Wednesday: Sunny to partly sunny, highs in the mid-80s, lows around 70 °F.
- Thursday: Mid-80s highs with a 50 % chance of showers and thunderstorms.
- Friday: Mostly dry, high near 80 °F, with a 30 % chance of overnight rain.
The NWS advises continued monitoring of updates as conditions evolve, particularly for those in flood-prone zones.
