MDOT SHA LogoHeavy Rain Associated with Coastal Low-Pressure System Could Make Driving Conditions Dangerous in Some Areas; Tidal Surge May Cause Localized Flooding in Several Areas Throughout the State (September 22, 2023) – The Maryland Department of Transportation State Highway Administration is preparing for a potential coastal low-pressure system that could impact much of the state beginning late Friday evening through Saturday. According to the latest forecast, the lower Eastern Shore and Southern Maryland counties will be most affected. Forecasters are predicting several foot Chesapeake Bay tidal surges associated with the storm, which will cause flooding in low-lying shore areas within the Chesapeake Bay watershed. This, along with heavy rain in some areas, may cause roadway flooding. Drivers are urged to take care of any business today to safely ride the storm out on Saturday into Sunday when the storm primarily impacts the state. State Highway Administration maintenance personnel are preparing for the potentially heavy rain by cleaning our drainage inlets, pipes, and ditches to ensure proper drainage and to reduce standing water on roadways. Additionally, State Highway Administration crews are inspecting generators to ensure proper operation, getting “High-Water” signs ready and ensuring its chainsaws are fueled, oiled and operational. State Highway Administration maintenance crews will continue monitoring the storm’s progress and will respond accordingly. The State Highway Administration reminds motorists to avoid travel unless necessary. If you are driving during a storm, or shortly after, you may encounter a variety of dangerous situations. Please take extreme caution if you must go out. Here are some tips for motorists. Do not try to cross a flooded roadway. Eighty percent of flood-related deaths occur in vehicles. “Turn Around.
