At airports, fog events can cause socio-economic damage during landing or takeoff. For the Zumbi dos Palmares International Airport, a tool was created to forecast low visibility by the Laboratory of Synoptic and Physical Meteorology at the Federal University of Alagoas, the Fog Visibility Version 1 (FogVISv1.0). The present study aims, therefore, through the forecasting data of the Brazilian developments on the Regional Atmospheric Modeling System (BRAMS) mesoscale model, to simulate the horizontal visibility through the liquid water content (LWC) and the concentration of the number of drops (Nd) for six fog episodes. It occurred at Zumbi dos Palmares International Airport between 2008 and 2014, lasting 1 hour or more, to analyze the capacity of the FogVISv1.0 tool with BRAMS model initial conditions, in detecting low visibility associated with fog events. The results show that 83% of the fog events recorded by the airport's surface station were forecasted, which totals five of the six cases evaluated.
