Back-to-Back Pacific Storms to Impact the West Coast; Heavy Snow in the Central Appalachians

Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >

Current Drought Maps

https://droughtmonitor.unl.edu/data/png/current/current_wfooax_trd.png		The categories of drought are defined as follows: Abnormally Dry (D0) - Going into drought: short-term dryness slowing planting, growth of crops or pastures; fire risk above average. Coming out of drought: some lingering water deficits; pastures or crops not fully recovered. Moderate Drought (D1) - Some damage to crops, pastures; fire risk high; streams, reservoirs, or wells low, some water shortages developing or imminent, voluntary water use restrictions requested. Severe Drought (D2) - Crop or pasture losses likely; fire risk very high; water shortages common; water restrictions imposed. Extreme Drought (D3) - Major crop/pasture losses; extreme fire danger; widespread water shortages or restrictions. Exceptional Drought (D4) - Exceptional and widespread crop/pasture losses; exceptional fire risk; shortages of water in reservoirs, streams, and wells, creating water emergencies.

Streamflow

The real-time streamflow map tracks short-term changes (over several hours) in rivers and streams. The daily streamflow map shows average streamflow conditions for the previous day. The 7, 14, and 28 day streamflow maps below show the average streamflow conditions, and are more indicative of longer-term streamflow conditions than either the real-time or the daily streamflow maps. The maps depict average streamflow conditions as computed at USGS streamgages. The colors represent average streamflow compared to percentiles of historical average streamflow for the day of the year. Only streamgages having at least 30 years of record are used.
