Crater Lake Sees Red Flag Warning and Unstable Weather on August 27, 2025

A Red Flag Warning was issued today for Crater Lake National Park, as dry, gusty winds and isolated thunderstorms elevate wildfire risk in the region.

Crater Lake, OR (Aug. 27, 2025) - The National Weather Service has placed the Crater Lake area under a Red Flag Warning from 1:00 PM until 9:00 PM PDT, citing critical fire weather conditions driven by low humidity, gusty winds, and the potential for dry lightning strikes. Park officials urge visitors and nearby residents to exercise extreme caution with any open flames or spark-producing activities during the warning period.

Temperatures in the Crater Lake vicinity are expected to reach a high of 68 °F today, with northwesterly winds gusting up to 15 mph. Humidity levels are forecast to remain below 30 percent through the afternoon. A slight chance of thunderstorms exists, though the drier atmospheric profile increases the likelihood that any lightning may not be accompanied by significant rainfall-a scenario that can rapidly ignite wildfires in the park’s forested slopes.

Crater Lake National Park remains open, but all visitors are reminded that trail conditions can change quickly under these weather patterns. The park’s avalanche-and-rockfall-prone trails, including the popular Rim Trail, may see increased debris or unstable conditions following gusty thunderstorms. Park rangers recommend checking the Current Conditions hotline at (541) 594-3100 or visiting nps.gov/crla before embarking on any backcountry excursions.

While no active wildfires are currently burning within park boundaries, the elevated fire danger heightens the risk of new ignitions. Fire suppression resources have been pre-positioned, and air quality advisories may be issued should smoke from any distant fires drift into the caldera. Visitors with respiratory sensitivities should plan accordingly.

For those seeking alternative activities during periods of high fire danger, scenic drives along West Rim Drive and overlooks at Watchman and Garfield peaks remain safe viewing options. Boat tours and lakeshore access via Cleetwood Cove are still available today, but operations are subject to weather-related delays.

Authorities ask everyone in the region to refrain from smoking outside designated areas, avoid parking on dry grass, and report any signs of smoke or unattended campfires immediately to park dispatch.

Ultimately, with critical fire weather forecast through this evening, Crater Lake visitors must remain vigilant and responsive to park alerts to ensure both personal safety and the preservation of this iconic natural landmark.
