Weather update 1 May 2018

The basic trail conditions are currently unchanged from my report yesterday. The temperature on the mountain (above 6000′) never got above freezing today, and a light snowfall seems likely tonight into tomorrow. We hiked early this morning from Humber Park to San Jacinto Peak, returning via Tahquitz Peak, and then checked the water sources in the Tahquitz meadows before descending Devils Slide Trail.

At San Jacinto Peak at 0900 this morning, the air temperature was 22°F (-5.5°C), but with a westerly wind gusting to nearly 20 mph, the wind chill temperature was as low as 6.3°F (-14°C). At that time the cloud level was below 7000′, but as we descended it rose to around 9000′. At Tahquitz Peak at 1200, we were in and out of the cloud and winds were lighter, and I recorded an air temperature of 25°F (-4°C) with a wind chill temp down to 17°F (-8°C).

We had no precipitation all day until we finally encountered some light drizzle below 6800′ as we descended Devils Slide Trail, but in Idyllwild it had barely rained (<0.1″).

Current forecasts project up to 2″ of snow above 5500′ elevation tonight into tomorrow morning, with up to about 3″ as high as San Jacinto Peak. I will update again tomorrow afternoon with revised trail conditions.
