(Premium only) Click Map Layers on the top toolbar and select one or more map layers that indicate current weather, weather alerts, and road surface conditions.
The Radar Layer shows location of precipitation and its intensity in decibels (dBZ). dBZ values increase as precipitation becomes more intense.

The Road Conditions Layer can help you identify areas where roads make be wet or icy due to recent weather. Zoom in for best results.
