SFMD cautioned hikers about heat-related illnesses after one person died on May 11. "As temperatures climb, so does the risk," SFMD said on social media. "Heat illness can set in fast, even for experienced hikers."

It also said most heat deaths happen on trails between 10 a.m. and 4 p.m. "Please stay safe and plan wisely. No hike is worth your life," SFMD said. SFMD recommends the following measures for hikers to stay safe in hot weather: Avoid hiking in extreme heat, especially during excessive heat warnings. Always carry more water than you think you'll need, minimum 1 liter per hour of hiking. Never hike alone, and always tell someone your route. If you feel dizzy, nauseous, stop sweating or become confused, get help immediately. This story has been updated with additional information.
