Use extreme caution if headed to area waterways this weekend. Area waterways are running very cold due to snow melt. Even strong swimmers could be in danger. Do NOT enter cold, fast-running water! #cawx

On this date last year, the state #snowpack was already at 177% of average. Today's results show improvements to the #snowpack , but warm storms in Feb. mean numbers are still lower than we’d like. Next month will be critical for #CA ’s water supplies forecast.
