If you’re headed into the Angeles National Forest or nearby valleys to hike over the next few days, be sure to bring extra water – the National Weather Service has issued a special advisory for high temperatures and humidity from now until early next week.

Daytime temperatures will peak above 100 degrees in the valleys this weekend, with some of the lower mountain elevations reaching around 105. If that doesn’t sound bad enough, higher humidity is supposed to move into the area between Friday and Sunday. Temperatures may drop a bit due to cloud cover, but the added moisture in the air will kick those heat index values up to critical levels.

If you’re going to be outside, be sure to load up on sunscreen and bring plenty of extra water. Wear head coverings for shade and don’t try to push yourself if you’re feeling exhausted. I’d also recommend hiking somewhere along the coast in the Santa Monica Mountains, where temperatures should be significantly cooler (upper 70s – low 80s on the shore itself, 90s further inland).
