What forecasters are seeing

Plain-English forecast narrative from the local NWS office. Issued by NWS SGX.

166 FXUS66 KSGX 190442 AFDSGX Area Forecast Discussion National Weather Service San Diego CA 942 PM PDT Mon May 18 2026 .SYNOPSIS... Night and morning low clouds and fog will be present each day through the forecast period along the coast for the first half of the week and into portions of the valleys towards the end of the week. High temperatures will be below average in the deserts today and tomorrow, with highs 5 to 10 degrees above average west of the mountains for the first half of the week. Minor fluctuations in temperatures for Thursday through next weekend. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... Weak offshore flow through Wednesday will keep low clouds out of the inland valleys but won`t be strong enough to keep coastal areas clear of low clouds overnight and in the mornings. It should help with more efficient clearing in the afternoons through Wednesday. A noticeable warming expected today compared to yesterday with the inland valleys expected to be 8 to 15 degrees warmer. An additional 3 to 7 degrees of warming is expected on Tuesday from the coast to the deserts, with continued warming inland Wednesday. The marine layer is expected to deepen Wednesday night into Thursday, which will push low clouds and fog into the inland valleys. A deeper marine layer is expected to be maintained through the weekend. There will be slight day-to-day differences in high temperatures for Thursday through next weekend with high temperatures a few to around 5 degrees above average. && .AVIATION... 190600Z...Coast/Coastal Valleys...Clear skies and VFR conditions prevail across the coastal basin tonight. Low chance (<10%) of marine layer cloud development across coastal San Diego County between 13-17z. If any low clouds do develop, bases would be AOA 1500ft MSL. Higher chances for marine layer clouds to return Tuesday night. Inland Valleys/Mountains/Deserts...Another round of northerly/easterly offshore winds pick back up after 18z Tuesday. Strongest gusts up to 25-30kts localized to mountain passes, closer to 20kts or less stretching below passes. Otherwise, VFR prevailing through the period. && .MARINE... No hazardous marine conditions are expected through Saturday. && .SGX WATCHES/WARNINGS/ADVISORIES... CA...None. PZ...None. && $$ PUBLIC...CO AVIATION/MARINE...Munyan

Mountain & avalanche safety

Know before you go
Check today's avalanche bulletin from the regional avalanche center before any off-piste / side-country / backcountry travel. Conditions can shift dramatically between morning and afternoon on storm days.
Carry the gear, know how to use it
Beacon, shovel, probe. Practice companion rescue on a calm day, not during a real burial.
Mind the weather window
Heavy snow + wind builds wind slabs at ridgelines. The day after a storm is often the riskiest in the backcountry, even if the resort itself is open.
Respect closed terrain
Ropes are there for a reason. Even in-bounds, ducking a closure can trigger a slide that catches you and others below.

FAQ

About Trinity Mountain Resort

Where does the snow data for Trinity Mountain Resort come from?

Snowpack, SWE, 24-hour snowfall, and air temperature come from the nearest USDA NRCS SNOTEL station. Forecast comes from the National Weather Service / yr.no feed that Snoflo's iOS app uses.

How often is the snow report updated?

Snowpack and SNOTEL data are updated continuously by NRCS (typically hourly). The 15-day weather forecast is refreshed throughout the day. Snoflo caches and renders the most recent observation -- look for the "as of" timestamp on the snowpack hero.

What's the elevation at Trinity Mountain Resort?

See the Resort Metrics panel above for base / summit / vertical drop. The summit elevation drives snowpack accumulation -- higher summits hold snow longer through spring.

How is "% of normal" calculated?

Today's snowpack is compared to the average snowpack on this calendar day across every recorded year at the nearest SNOTEL. 100% means right on average; 130% is a big year; 60% is thin.

What ski resorts are near Trinity Mountain Resort?

See the Other Ski Areas pill grid at the bottom of the page for resorts within driving distance. The sister Other Ski Areas card in the Plan-a-longer-trip grid above shows the closest few.

Can I get alerts when fresh snow hits?

Yes -- snow alerts are managed in the Snoflo iOS app. Favorite this resort, set a snowfall threshold (e.g. "alert me when 6+ inches"), and you'll get a push the moment the SNOTEL crosses.
