The National Forest Service announced Friday afternoon that popular hiking trails in Ramona would be closed through Monday because of the heat wave.
“Hikers suffering from heat-related illness is common during the summer, thus the need to close the area,” the forest service said.
Highs Saturday are expected to be 89 to 94 in the western valleys and 97 to 102 near the foothills,
The two trails are located east of Ramona near the San Diego Country Estates subdivision.
The trails are particularly difficult in heat, and hikers frequently become dehydrated and have to be rescued by helicopter.
