The latest from NWS, showing the rain starting Monday and with higher rainfall totals now:
THE CENTRAL CALIFORNIA INTERIOR WILL SEE A SIGNIFICANT CHANGE TO A WET WEATHER PATTERN NEXT WEEK. A LOW PRESSURE SYSTEM WILL APPROACH THE WEST COAST FROM THE WESTERN PACIFIC ON MONDAY. THIS SYSTEM IS EXPECTED TO BRING COOLER TEMPERATURES AND THE POTENTIAL FOR SIGNIFICANT PRECIPITATION DUE TO EMBEDDED MOISTURE FROM THE REMNANTS OF RECENT SUPER TYPHOON MELOR.
HEAVIEST PRECIPITATION WILL BE OVER THE NORTHERN HALF OF THE FORECAST AREA...INCLUDING THE CENTRAL SAN JOAQUIN VALLEY...THE SIERRA NEVADA...AND THE SURROUNDING FOOTHILLS MAINLY NORTH OF KINGS CANYON. THE BULK OF THE PRECIPITATION WILL LIKELY OCCUR MONDAY NIGHT THROUGH TUESDAY NIGHT WITH LINGERING SHOWERS ON WEDNESDAY.
CURRENTLY...RAINFALL TOTALS ARE ESTIMATED TO RANGE FROM 2 INCHES OVER THE CENTRAL SAN JOAQUIN VALLEY...TO NEAR 5 INCHES IN THE FOOTHILLS AND HIGHER ELEVATIONS OF THE SIERRA NEVADA. IMPACTS FROM THIS RAINFALL COULD INCLUDE URBAN AND SMALL STREAM FLOODING...AND DEBRIS FLOWS ON RECENT WILDFIRE BURN SCARS WHERE HEAVIEST AMOUNTS OCCUR.
THIS SYSTEM WILL REMAIN FAIRLY WARM WITH SNOW LEVELS EXPECTED TO REMAIN HIGH...MAINLY ABOVE 8000 FEET. WINDS FOR MONDAY THROUGH WEDNESDAY ARE EXPECTED TO BE BREEZY WITH THIS SYSTEM...ALTHOUGH THERE COULD BE STRONG WINDS OVER THE SIERRA NEVADA CREST. TREES WEAKENED FROM RECENT FIRES COULD ALSO BE DOWNED BY THESE WINDS.
OUTDOOR ENTHUSIASTS...ESPECIALLY CLIMBERS AND PEOPLE IN THE BACK COUNTRY...SHOULD BE PREPARED FOR THE CHANGE TO WET AND BREEZY CONDITIONS NEXT WEEK. MOTORISTS SHOULD CHECK ROAD CONDITIONS...ESPECIALLY OVER HIGHER PASSES NEXT WEEK.
The storm itself looks like it could impact the first half of the first day of the workshop schedule, but that is still aways out.
However, the forecasted strong downslope winds over the Sierra crest would impact the fall colors as it would blow the leaves off the trees, especially in the Bishop/Aspendell region.
Also, snow/mud could impact the road to Bodie ghost town. That will be determined at the start of the workshop. But rest assured I have several contingency locations in the event the weather does impact our schedule.
Please drive safe in this storm on Tuesday/Wednesday. With snow levels at 8500 feet, it is a guarantee that Tioga Pass (Highway 120) in Yosemite will be closed at the onset of the storm on Monday, as well as Sonora Pass (Highway 108) and Ebbett's Pass (Highay 4).
