116 FNCA52 TJSJ 240826 FWFSJU Fire Weather Planning Forecast for Puerto Rico National Weather Service San Juan PR 426 AM AST Tue Sep 24 2024 .DISCUSSION... The RH values across the southern, southwestern and parts of the north coast of Puerto Rico will drop to as low as the mid 50s, but KBDI values will remain much below critical thresholds, except for Guanica has now reached 550 due to persistent sunny skies and high temperatures. Fortunately 10 hour fuel moistures are in the mid teens. Also, the winds will be below 15 mph. There is a continued risk of thunderstorms, but nevertheless, the risk of dangerous fire behavior will remain low through the week. We expect winds to increase on Wednesday as warm to hot weather continues.
