Icy Roads Forecasting & Monitoring Dashboard (LCR & BFP+ Charts)

Important Disclaimers: The system producing these charts uses numerical model data from NOAA servers, but this site and these charts are not associated with nor endorsed by NOAA or the National Weather Service. These charts should not be used as official forecasts, but rather as model guidance products. The LCR scale is experimental and the system producing these charts is in a beta stage of development.

Note: You may need to refresh the page to see the newest charts. Visit the LCR main page for complete documentation.

Explanation of Parameters

LCR (Loss-of-Control Risk): The risk of a motor vehicle losing control due to reduced road surface friction from winter precipitation. Based on 1-hour precipitation amounts (QPF), precipitation type, surface temperature, surface dewpoint, surface relative humidity and surface wind gusts. LCR charts show the maximum values of LCR expected during the time period represented on the chart. See the main LCR page for detailed synopsis of LCR calculation.

BFP+: BFP Plus charts show the following four data sets together:

  • CIP (Precipitation at/below Critical Icing Temperature): The amount of precipitation (QPF) of any type occurring where surface temperatures are at or below 29.9°F.
  • BFP (Below-Freezing Precipitation): The amount of precipitation (QPF) of any type occurring where surface temperatures are at or below freezing (32.9°F).
  • NFP (Near-Freezing Precipitation): The amount of precipitation (QPF) of any type occurring where surface temperatures are between 32 and 38 degrees Fahrenheit.
  • AFP (Above-Freezing Precipitation): The amount of precipitation (QPF) of any type occurring where surface temperatures are above 38 degrees Fahrenheit.
The scale used on BFP, NFP and AFP is zero to 0.1 inches of liquid-equivalent precipitation of any type (rain, snow, sleet, graupel, freezing rain, freezing drizzle, drizzle). Precipitation amounts above 0.1 inches are represented at the same color as 0.1 inches.
