The center of Hurricane Marie is expected to remain well to the southwest of the area through the holiday weekend. Surf from Marie will begin to arrive tonight and is expected peak on Sunday, then only slowly subside for Monday into Tuesday. Mid and high level moisture from Marie will bring the greatest chances for showers on Sunday. Then warmer and gradually drier for Monday through Wednesday of next week. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... .SHORT TERM (Today through Sunday)... Hurricane Marie remains on a track toward the west-northwest with the center to remain well to the southwest of the area through the holiday weekend. The current NHC forecast has Marie weakening to a tropical storm on Sunday. A dry air mass remains in place across inland areas early today and high temperatures for inland areas will remain around 5 to 10 degrees below average for today. High temperatures for today will range from the mid 70s near the coast to the mid to upper 80s for the Inland Empire with the lower deserts around 100. Swell and resulting surf from Hurricane Marie will begin to increase for the beaches for Orange and San Diego Counties for tonight and Saturday with the highest surf for late Saturday night into Sunday evening with the the highest surf from Oceanside northward. Mid and high level moisture from Marie will begin to increase from the south for late tonight and Saturday with a chance of showers for portions of San Diego County on Saturday afternoon. The moisture will continue to increase and spread northward for Saturday night and Sunday. For Sunday night and Monday, the chance for 0.25 inch or more of rainfall for the coast and valleys is 5 to 15 percent. For the mountains, the chance for 0.25 inch or more of rainfall is 20 to 40 percent with the chance for one inch or more less than 10 percent. Thunderstorm probabilities remain highest on Sunday afternoon, but are now less than 15 percent. && .LONG TERM (Labor Day through Thursday)... Higher surf will continue into Labor Day, then slowly subside into Tuesday and Wednesday. Mid and higher level tropical moisture will be decreasing on Labor Day into Tuesday. Warmer nights will continue into early next week with warmer high temperatures for Labor Day through Wednesday as drying occurs. High temperatures for next Wednesday will be within a few degrees of average for the mountains and deserts and a few to around 5 degrees above average for the coast and valleys. High temperatures for next Wednesday will range from around 80 near the coast to the 90s for the Inland Empire with the lower deserts around 105. Low temperatures will be mostly in the mid 60s to lower 70s for the coast and valleys and in the mid 70s to mid 80s for the lower deserts. && .AVIATION... 040530Z...Coast/Valleys...A few low clouds based 1,500-2,000ft MSL have been moving in and out along the coast the past few hours.

A large south swell from Hurricane Marie will move into the region Friday night and Saturday, peaking Sunday into Monday, before gradually diminishing Tuesday. This will result in elevated to high surf and strong rip and longshore currents at majority of beaches. Additionally, waves will occasionally run much farther up the beach than expected, especially during increasing and evening high tides. For south and southwest-facing beaches, expecting high surf 6-10 feet. This includes Orange County and north San Diego County beaches. For west-facing beaches, expecting elevated surf 4-7 feet. This includes most of southern San Diego County beaches. High surf combined with high astronomical tides 6 to about 6.5 feet will lead to tidal overflow and coastal flooding Saturday through Tuesday during evening high tides, especially for those south and southwest-facing beaches as well as low-lying, typically impacted areas. && .SKYWARN... Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. && .SGX WATCHES/WARNINGS/ADVISORIES...

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.
