Displays flood and flash flood reports as well as intense rainfall observations for user-selectable time ranges and customizable geographic regions. Includes ability to download reports and associated metadata in csv format.
Plots of GEFS probabilistic forecast of precipitation, temperature, and sea-level pressure exceeding various thresholds.
Custom plots of Local Storm Reports across the Contiguous United States. Reports include rain, snow, ice, and severe weather, as well as other significant information from storm spotters.
Displays the climatological significance of precipitation forecast by WPC. The climatological significance is represented by Average Recurrence Intervals (ARIs) of precipitation estimates from NOAA Atlas-14 and Atlas2.
An interactive situational awareness table that displays anomalies, percentiles, and return intervals from the GEFS, NAEFS, and ECMWF Ensembles (login required to view ECMWF data).
*Please note that there is currently an issue where only users on a NOAA network can access this page. We are actively working to resolve this problem.
Interactive display of where temperatures could approach or exceed records within the contiguous U.S. (based on NDFD temperature forecasts)
Displays Days 1-7 NDFD maximum and minimum temperatures, along with their respective departures from climatology.
An interactive tool that depicts areas of heavy snowfall from individual members of high-resolution short range ensemble forecasts.
Displays forecast information and its climatological context to quickly alert a forecaster when a record or neear-record breaking event is possible. This tool is available for both CONUS and Alaska.
Interface for specialized WPC Excessive Rainfall Outlook Maps for NWS County Warning Areas and States.
Analog guidance that uses an objective approach to find historical events that are similar to the upcoming forecast.
Nationally consistent and skillful suite of calibrated forecast guidance based on a blend of both NWS and non-NWS numerical weather prediction model data and post-processed model guidance.
A portal for atmospheric river forecasts and diagnostics from the Center for Western Weather and Water Extremes.
An interactive display of time series plots from GEFS ensemble members at a point.
A variety of useful tools generated at The Storm Prediction Center (SPC).
Output from the ECMWF 'Ensemble Prediction System' (ENS) for four parameters: mean sea level pressure, 850 hPa temperature, 850 hPa wind speed, and 500 hPa geopotential height.
