Alerts

Alerts include important and timely information about conditions that may affect visits to a national park, group of parks, or larger area. There are four types of alerts, including:
  • Danger: Description of imminent hazard
  • Closure: Notification that the park, a major facility, or area within the park is inaccessible for some reason unrelated to an immediate safety concern
  • Caution: Description of a possibly hazardous situation
  • Information: Notification of something that may affect visitor plans
To see all alerts in effect across the Chesapeake Bay watershed, visit the Active Alerts in Parks page. You can filter alerts by park or type. You can also find alerts on each national park's website.

Note: These alerts only inform visitors of conditions and closures within national parks.
