The Road Weather Information System
(RWIS) is a network of meteorological and pavement sensors located
along the highway system. RWIS stations are located in strategic
locations to provide accurate real-time road weather information
and critical observations for forecasts. This and other weather
information helps Alaska Department of Transportation & Public
Facilities improve timeliness of maintenance actions, like when to
snowplow or deposit anti-icing/de-icing chemicals on the highways.
For more information see About RWIS.
