The fire simulator, FARSITE, requires two
types of input weather files - a WTR file containing daily summaries of temperature, relative humidity and precipitation, and a WND file
with hourly data of wind speed, wind direction, and cloud cover. Both files are in text (ASCII) format. This page allows you to retrieve these input weather files for the above
location using real-time forecast information generated by RMC. The weather files can be used with FARSITE to predict the likely behavior of a wild fire up
to 72 hours into the future.
