Lightning poses a serious threat to boaters. If you get caught on your boat during a thunderstorm, stay inside your cabin and avoid touching metal or electrical devices. If your boat doesn't have a cabin, then stay as low as you can in your boat.

To avoid being caught on the water during a thunderstorm, always have your NOAA weather radio or VHF radio tuned into the weather so you can stay informed and take action when adverse weather threatens. Learn more about what to do when weather changes while on the water by checking out weather.gov/safety/safeboating-during. Safe Boating Campaign #SafeBoating

Is Columbia MD going to get some of the severe weather or no?
Sleet in Columbia, MD. Has turned back to mostly rain with the lighter intensity now.
Siding damage from measured wind gust of 51 MPH. Belle Grove area (.75 mile south of I-68/exit 72; eastern Allegany County, MD).
FYI, some of us in the extreme southern end of your area (Charlottesville area) sometimes feel a little neglected. Your 11 pm post last night mentioned strong storms outside the DC/Baltimore area...trust me, it was pretty exciting down here as well!
