Description: This guidance is based on the GFS Model output and uses a modified version of the Stoelinga and Warner algorithm used in the eta mesoscale model. The GRIB output files have output in meters from 0 - 20,000 meters. This graphical display on this web site is designed primarily for the use of mariners. Visibilities at or below 1 km (0.5 n mi) are given in yellow; visibilities > than 1 km, but <= 5.6 km (3.0 n mi) are green, and visibilities > 5.6 km, but <= 13.0 km (7.0 n mi) are in blue anything > 13.0 km and le 20.0 km are white. The animations and still figures are in gif format; the animations are on the order of 2 Mb, while the stills are on the order of 15k each. Model output is available throughout the year.
