Residents in the affected counties should prepare for potentially hazardous weather conditions, including damaging winds and localized street flooding due to heavy rainfall. The risk of a brief tornado, while low, is not negligible, especially in areas west and south of Baltimore. Frequent lightning poses an additional safety concern. Those in central Maryland and the Baltimore metro area should remain vigilant during the peak storm window. The severe weather risk is expected to diminish after midnight, though scattered showers and storms may persist into early Monday morning.
