318 FNCA52 TJSJ 230941 FWFSJU Fire Weather Planning Forecast for Puerto Rico National Weather Service San Juan PR 541 AM AST Mon Sep 23 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 which is approaching 550 due to persistent sunny skies and high temperatures. Also, the winds will be well below 15 mph (very weak winds). As a result, the risk of dangerous fire behavior will remain low throughout at least until next week.
