Three snow storms in very quick succession impacted the region across four days on 16th-19th February. Although technically three separate storms, the impact on the mountain and trail system has functioned as one major storm, with the most substantial (so far) snowfall of winter 2025/26, especially at mid elevations.
Although the combined 26 inches of new snow around the highest peaks was desperately needed and is of course extremely welcome, this was at the lowest end of the forecast expectations, and hopes for 3-5 feet of snow were not ultimately realized.
I recorded a rather-too-lengthy video report from 10,350 ft on the east slope of San Jacinto Peak mid morning of Friday 20th February that summarizes the three storms and current conditions (linked here).
Snow fell in three distinct periods, on the afternoon and evening of Monday 16th, then again overnight on 17th-18th, followed by a much more minor snowfall on the evening of Thursday 19th. As was widely forecast this latest storm pattern was significantly colder than others so far this season, with freeze levels more typical of the historical average (at or below 5000 ft for much of the storm period). Consequently there was considerable snowfall at mid elevations, with the first snow of the winter recorded, for example, in Idyllwild (12.5 inches at 5550 ft across the four days), and with all three storms dusting down into Garner Valley (4400 ft).
As is increasingly the trend with a rapidly changing climate in recent years, there was relatively little difference in snowfall between the mid and upper elevations, with 12.5 inches measured in Idyllwild (at 5550 ft) through to 26 inches at San Jacinto Peak (10,810 ft). Locations on the western side of the mountain range, especially those in and around Strawberry Valley, received disproportionately more snowfall, as those areas were “socked in” by storms originating from the south-west, while the highest elevations were, at times, above the cloud.
Currently few trails have been traveled and most are obscured by significant snowfall. On my descent on Friday 20th I was surprised to see no tracks up to Saddle Junction or indeed anywhere on Devil’s Slide Trail. The significance of this is that there are currently no tracks on Willow Creek Trail, to Chinquapin Flat or Tahquitz Peak, or around the meadows. Cautious navigation is strongly recommended everywhere.
Snow depths are currently ideal for snowshoeing everywhere above about 6000 ft, potentially lower on less exposed trails that will melt slowly (e.g., the Ernie Maxwell Trail). Elsewhere (and in addition), spikes are recommended for the foreseeable future as established trails will eventually become consolidated by hiker traffic and will undergo freeze-thaw cycles.
Snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow several feet deep is often much easier hiking than traversing across just a few inches depth of angled virgin icy snow.
The USFS gate at Humber Park closed on 18th February. While theoretically nine legal parking spaces remain immediately below the gate, an unconventional ploughing approach this time has left space for only 3-4 vehicles to safely park. Conditions in the area are very icy and currently only suitable for 4WD/AWD vehicles anyway, and this area is best avoided this weekend in the absence of further ploughing. Parking on Forest Drive, just below the Fern Valley Water District facility, is strongly recommended.
Black Mountain Road (4S01) is closed at the gate 1.7 miles up from Highway 243. Following superficial grading late in 2025 the road is in better condition than last summer, but remains far rougher than in June 2020, the last time it was thoroughly graded. The gate for South Ridge Road (5S11) remained inexplicably open as of 18th February, although the road is under 12+ inches of snow and impassable at present.
Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically 2-3 times per week (but almost daily during winter storm weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER
Temperatures rise rapidly starting Friday 20th, and will be above seasonal in the last week of February. Temperatures are forecast to be above freezing >10,000 ft elevation for the remainder of the month, and with clear, sunny days expected, melting of snow will be rapid, especially on sun-exposed slopes. Temperatures are tentatively forecast to cool closer to seasonal in the first week of March, but by then much of the damage (in terms of snowmelt) may have been done.
The storm system on 16th-19th February consisted of three distinct phases, with the majority of the snow in the high country in the first storm, overnight on 16th. At mid elevations, the first phase was mild enough to initially produce rain, with 0.57 inches in Idyllwild, before turning to snow around dusk on 16th. The second phase was overnight on 17th, with bulk of the high country snow actually falling in the early hours of Wednesday 18th (about half the depth of the previous day). Finally the third storm passed through on Thursday 19th, with much lighter snow falling throughout much of the day, from late morning until just after dusk.
At San Jacinto Peak (10,810 ft/3295 m) on Friday 20th February 2026 at 0740 the air temperature was 17.8°F (-8°C),with a windchill temperature of -7.1°F (-22°C), 49% relative humidity, and a wild WNW wind sustained at 22 mph gusting to 36.2 mph.
At the Peak on Thursday 19th February 2026 at 1010 the air temperature was 15.3°F (-9°C), with a windchill temperature of -6.2°F (-21°C), 100% relative humidity, and a frigid WSW wind sustained at 14 mph gusting to 22.3 mph.
At the Peak on Tuesday 17th February 2026 at 0830 the air temperature was 11.0°F (-12°C), with a windchill temperature of -11.2°F (-24°C), 100% relative humidity, and a steady due West wind sustained at 18 mph gusting to 24.2 mph.
At the Peak on Monday 16th February 2026 at 1410 the air temperature was 23.9°F (-5°C), with a windchill temperature of 5.5 °F (-15°C), 100% relative humidity, and a subdued SW wind sustained at 12 mph gusting to 21.1 mph.

TRAIL CONDITIONS
All trails above about 5500 ft are completely snow-covered. By the afternoon of Friday 20th, melting was already well underway below 7000 ft.
Reliable tracks are currently only known to be in place for Devil’s Slide Trail through to San Jacinto Peak via Wellman Divide. The conditions of trails will likely change very rapidly with a weekend of pleasant and mild weather upcoming. At elevations above 10,000 ft strong winds persisted on 20th and will have quickly eliminated any prior tracks.
Snow depths are currently ideal for snowshoeing everywhere above about 6000 ft, potentially lower on less exposed trails that will melt slowly (e.g., the Ernie Maxwell Trail). Elsewhere (and in addition), spikes are recommended for the foreseeable future as established trails become consolidated by hiker traffic and undergo freeze-thaw cycles. Crampons would be a possibility at the highest elevations for the next few days, but warming is forecast to be so rapid that severe postholing may soon become a problem.
Current forecasts suggest that there may be no more precipitation for at least 2-3 weeks, with rapid warming and melting likely at all elevations. Days of freeze-thaw cycles will make the snow-ice conditions additionally challenging and variable.
In prior winters I have mentioned the challenges of hard, icy snow underfoot and the value of using spikes especially for descending and traversing. Snow at all elevations will become increasingly firm and icy following multiple freeze-thaw cycles, and I cannot overemphasize the importance of having both appropriate equipment and the right skill set for the terrain. The latter includes interpreting the snow/ice conditions, understanding your physical and mental abilities, and conservative decision making. These concerns may steadily increase over the next couple of weeks with dramatically rising then falling temperatures, seasonally stronger insolation, and highly variable snowmelt.
Early on the morning of Saturday 21st we broke trail through light to moderate depth snow on South Ridge Road and South Ridge Trail to Tahquitz Peak (photos below). At that time these routes were untraveled, but by the time we descended, a few other hikers were postholing through rapidly softening snow at least part way to the peak. The only safety challenge was on the uppermost switchbacks above about 8400 ft, where the snow slopes were largely continuous (with no obvious trail topography), requiring significant caution for traversing. This issue will diminish as more hiker traffic generates a better-defined track.
The 0.4 mile section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak currently has no track to follow through steeply angled icy snow. These icy slopes on the north side of Tahquitz Peak are notoriously treacherous. Currently crampons with an ice axe, and the requisite skills to use this equipment in high angle terrain, are critical.
