Storm surge FAQs for National Harbor

Can storm surge affect National Harbor?

Surge risk generally drops quickly inland, but tidal rivers and bays can still push water farther than expected in some storms.

Is storm surge the same as flooding?

Surge is ocean water pushed onshore by wind/pressure; flooding can also come from rainfall, rivers, and drainage issues.
