Tropical storm Isaias is expected to make landfall tonight in the Carolinas as a hurricane. Marylanders can expect to feel effects from Isaias beginning tonight, but the greatest impacts are expected Tuesday. Heavy rain is expected in central and eastern Maryland, with as much as 5-7 inches of rainfall forecasted, and flash floods and tidal flooding are likely. Heavy winds could topple trees and cause power outages. A westward shift in the storm track could also create a greater impact in western Maryland.
