Heavy Precipitation in the West; Wintry Mix in the North; Fire Weather in the High Plains

Pacific moisture will continue to bring locally heavy coastal/lower elevation rain and heavy mountain snow to the West Coast and portions of the Intermountain West through Monday. A wintry mix will create hazardous travel across the northern Plains and Upper Midwest into early Monday. Dry, gusty winds are resulting in elevated to critical fire weather in the south/central High Plains. Read More >

Changes are coming to NWS hydrology products. They were implemented at NWS Milwaukee on Nov 15. You'll notice it the next time we issue any of these products.

Why?

The NWS wants to simplify the communication of information and improve the understanding and utility of forecasts and warnings.

This is part of a larger hazard simplification project and there will be changes to other weather products over the next few years.

Flash Flood Watch and Flood Watch will be consolidated to Flood Watch*.

* Flash Flood Watches will still be issued due to possibility of flash flooding due to possible dam failure

Urban and Small Stream Flood Advisory, Small Stream Flood Advisory, Flood Advisory, Hydrologic Advisory will be consolidated to Flood Advisory

The wording within the Flood Watch/Warning, River Flood Watch/Warning, and Flood Advisory will be reformatted with What, Where, When, Impacts, Additional Details. This has already been done for Flash Flood Warnings.
