Does Washington D.C. get hurricanes?
Direct hurricane hits are rare, but the region can see remnants bring heavy rain and gusty winds from late August through October. If a tropical system approaches, monitor the dc weather radar and local alerts. The city’s location inland from the Atlantic reduces storm surge risk.
