Three Sisters Falls Trail Closed Due to Heat

A popular hiking trail in San Diego County was closed Tuesday due to high heat and public safety concerns, according to the Cleveland National Forest.

Three Sisters Falls, located near Julian, will be closed until Wednesday, as the heat wave scorches parts of the county.

There were five medical evacuations on the trail Tuesday. Over the weekend into Monday, eight hikers were rescued on the trail.

A heat advisory was in effect for San Diego's inland valleys and foothills, including Santee, El Cajon and Escondido, through 9 p.m. Wednesday, where temperatures are expected to hit between 95 and 103 degrees.

A statewide Flex Alert was also issued Monday by the California Independent System Operation Corporation (ISO), asking residents to voluntarily conserve electricity through Wednesday evening.
