Wet week to start February over most of the region. Highest precipitation amounts are around 13-26 inches over the Nrn Sierra and 9-20 inches over the Shasta Basin since Feb 1. More widespread precip is expected mid-late next week. #cawx #cawater #nvwx

Areas of heavier rainfall over Srn CA could produce sharp rises on rivers. The Santa Margarita River at Ysidora (27% chance) and San Diego River at Fashion Valley (11% chance) have a greater than 10% chance of action/monitor stage in the next five days. #cawx #cawater

Showers & slight chance t-storms mainly ovr Central & Srn CA & most of NV into Monday. 1-3" fcst ovr transverse range to San Diego Cty Mtns & 0.75-1.5" Srn CA coast. Freezing levels drop to 3-5 kft Sun. Lingering showers Srn CA Tues-Wed. Precip in N late Thurs-Fri #CAwx #nvwx

As we end the "1st Quarter" of the 2025 WY, total precip as % of avg shows those areas running "ahead of the game" (northern CA, especially Eel/Russian and Sacramento basins), and those that are not (central/southern CA and NV, especially southern CA and southern NV). #CAwx #NVwx

A weaker system bringing periods of light to moderate precip to Srn OR & Nrn CA & portions of Central CA & NV into early Tuesday. Generally dry later Tues-early Friday except showers possible NW CA & Srn OR Cascades Wednesday. A stronger system expected late Fri-Saturday. #cawx

More precip, mainly light to moderate, is forecast over Srn OR & Nrn CA & portions of Central CA & Nrn NV tonight into early Tuesday. A few river locations remain above monitor stage and flow at Colusa and Fremont weirs. Additional precip expected next weekend! #cawx #Nvwx

How much precip fell over CA/NV in the last 48 hrs ending at 4 am today? Highest precip amounts were 3-6" with local amounts to ~8 inches along the Nrn CA coast & Shasta Basin. Rivers rose to monitor stage at several points & a few points to Minor flood stage. #cawx #cawater

After a prolonged dry spell to start the month of December, we are finally seeing a pattern shift that will bring widespread precip back to the region starting later today, especially northern CA. Here are forecast precip amounts through next Tuesday morning. #CAwx #NVwx

The #RussianRiver saw significant rises with the heavy precip that affected the basin over the past 3 days. The flood wave is currently moving past #Guerneville with the river cresting (34.68 feet) shy of the "Moderate Flood" stage (35 ft). River will recede this weekend. #CAwx

Impressive 3-Day totals across northern CA! Observed amounts of 7" to 14" (locally 15" to 22") from the Eel to Russian/Napa River basins along the coast, and Shasta Lake drainage to the Feather River basin over the southern Cascades/northern Sierra. #CAwx #CAwater #CAflood
