The visibility is indicated on the map by different colors for the following ranges: 0 - 0.24, 0.25 - 0.49, 0.5 - 0.74, 0.75 - 0.99, 1.0 - 2.9, 3.0 - 4.9, 5.0 - 6.9, and 7.0+ miles, in order to correspond with thresholds important to mariners and aviators as well as thresholds associated with visibility-related watches, warnings and advisories issued by the National Weather Service.

This nowCOAST™ time-enabled map service provides maps depicting the past four hours of surface meteorological analyses of air temperature, dew point temperature, visibility, wind velocity, wind speed, wind gust, and 1-hr accumulated precipitation from the NWS/NCEP Real-Time Mesoscale Analysis (RTMA) system. The horizontal spatial resolution depends on geographic region: 2.5 km (1.6 miles) horizontal resolution for CONUS, Hawaii, Puerto Rico and Guam and 3 km (1.86 miles) for Alaska region.
