South to southeast winds will occasionally gust around 20 knots from late this afternoon into this evening. This is most likely to occur in the middle Chesapeake Bay and lower tidal Potomac River. Inexperienced mariners, especially those operating smaller vessels, should exercise extra caution if navigating the waters during that time.

A combination of dry and windy conditions this afternoon will create an elevated risk of wildfire spread across Central Pennsylvania. Minimum relative humidity values will range from 20 to 30 percent accompanied by southerly wind gusts between 20 and 30 mph. Residents are urged to exercise caution if handling any potential ignition sources, such as machinery, cigarettes, or matches. Hold on to your cigarette butts! If dry grasses and tree litter begin to burn, the fire will have the potential to spread rapidly.
