Areas of Critical Fire Weather in the Central U.S.; Pacific Storm to Impact California Midweek

Dry and windy conditions will bring critical fire weather to much of the northern and central Plains today, then critical fire weather is expected across New Mexico into the southern Plains Tuesday into Saturday. A Pacific storm with atmospheric river will bring heavy mountain snow and strong winds to the Sierra Nevada and heavy rainfall over parts of coastal southern California midweek. Read More >

Coverage Map Notes

The coverage statistics and maps are calculated using a computer model and station data assuming ideal conditions. Coverage may be 5 to 10 percent below the computer predicted coverage for the following reasons:

  • The computer model is sensitive to antenna performance. Antenna performance is a function of local conditions, causing signals to be stronger signal level in some directions than others.
  • Placement of NWR antennas is dictated by the tower owner, which may result in a less than ideal set up.
  • The antenna may be affected by nearby structures or bodies of water.
  • In some special instances, the antenna may have been intentionally adjusted to be "directional" and provide better coverage to a specific area to the detriment of other areas.
  • Because of variations in local site conditions, the performance of an individual transmitter and antenna may be less than predicted or expected.
  • Seasonal environmental conditions, such as icing or heavy rain, affect performance of a transmitter station and its various components, particularly those subject to continuous weather exposure.
  • The coverage maps are shown in a single color format, which relates to an estimated signal level.
    • White: Signal level of greater than 18dBuV: Reliable coverage
