How does a road weather forecast differ from the forecast I see on the news at night?
|
|
A road weather forecast only concentrates on weather that impacts travel. For
example, 3 inches of snow might be forecast to stick on the grass, but roads may remain
wet.

What is an RWIS?
|
|
RWIS stands for Road Weather Information System. UDOT maintains a network of
RWIS weather stations across the state of Utah. RWIS stations have atmospheric
sensors, road sensors and cameras. These instruments measure air temperature, wind
speed and direction, precipitation, road temperature, road surface condition, and other
variables.

|
What do you do with the information you collect from RWIS sites and how does it
help me travel?
|
|
RWIS stations provide critical information to a team of UDOT meteorologists and
plow crews to help keep roads free of snow. RWIS stations also help inform the public
of what the road conditions are like around the state.
