¡Buenos días, my friends
Cup’☕️ ’Joe in hand, , Frothy @14.9. Second straight morning with an empty board. The 0142 AFD out of NWS Reno lists no watches, no warnings, no advisories for either California or Nevada. The shortwave that ran us for three days has exited north, and high pressure is building over the Great Basin, so the airmass over the basin is drier and more stable than it has been all week.
Here is the honest shape of the day, and it is a day of two halves. Sunny and 73º degrees at the shore, with the lake zone 70º to 77º. Sunrise to 1100 is the prize: 2 to 4 knots of glass on 69.2º water with waves under a foot. Then the switch throws around 1300, and the westerly zephyr fills, 10 gusting 12 knots at 1400 and topping out at 12 gusting 14 knots WSW at 1700 before it quits by 2000. That is roughly double yesterday's ceiling. Mornings belong to Surf, SUP, and Foil. The afternoon finally gives Sail krews something real to work with. If you want the land option, Tallac goes cool at dawn, and the Pope-Baldwin path is clean before it fills up. UV is very high under a cloudless ridge, so cover up. Sunrise 0613, sunset 1954.
The week ahead is the most settled stretch since late July. High pressure locks in and holds: sunny 76º Sunday, 78º Monday, 79º Tuesday, 80º Wednesday and Thursday, 79º Friday, nights 47º to 52º, with a daily afternoon zephyr and ridge gusts 20 to 22 knots. Waves stay under a foot all seven days. Water reads 69.2º, down a tenth on the morning comparison, and lake level is flat at 6,228.29 for a third day. The only weather anywhere in the region is a 15 percent chance of evening storms over Mineral County, far to the southeast. Watch the 22nd, where the GEFS breaks the ridge down for a monsoon return, and the European ensemble keeps it east.
Two tracks worth your attention. On the Super El Niño watch, CPC's August 13 discussion moved the numbers up: better than 90 percent odds of a very strong event through both fall and winter, and a 69 percent chance the October through December season sets a record going back to 1950. MEI.v2 for June and July came in at plus 2.41, the highest in the modern record. One caution, because these get mixed constantly, CPC states its odds in RONI, not the conventional Niño3.4 reading of plus 2.6. A very strong El Niño loads the dice for a wet Sierra without settling which half of the range collects. . AND the caveat insert - WE have a few MET's tracking, citing, and calling for the Niño-heavy to be primarily targeted over the lower-half of CA, yes, SoCal, New Mexico, Arizona…
Down south, the access story is the story, and I owe you a correction. Yesterday I reported that Portillo's road reopened on August 10. It did not. Paso Los Libertadores has been closed continuously since July 14; today is day 33, the longest shutdown since the crossing opened in 1980. The detail that matters: the roadway itself has been cleared with both lanes usable since late July, but Chile holds it administratively closed because Ruta 60-CH doubles as the international freight corridor, so Portillo sits four to five km below a shut border pass looking at clean pavement it cannot use. The resort is open anyway, turning 12 of 14 lifts on 283 cm, reaching guests by helicopter. More than 1,550 trucks are parked on the Argentine side, costing roughly 1.2 million dollars a day, and the government points to Monday the 17th as an evaluation date, not a promise. Valle Nevado takes 37 to 38 cm today with all 13 lifts and all 45 slopes open. Termas de Chillan holds 124 cm at the summit with 15 lifts running. Australia is the mirror image: Spencers Creek measured 94.5 cm, already past the 85.1 cm of 2006 but running a little under half the long-term average peak near 195 cm, with Thredbo spinning all 15 lifts on nothing new in 48 hours. New Zealand holds firm spring corduroy, Mt Hutt 109 to 170 cm.

you.” ― Dalai Lama XIV
