FNCA52 TJSJ 210942 FWFSJU Fire Weather Planning Forecast for Puerto Rico National Weather Service San Juan PR 542 AM AST Thu Nov 21 2024 .DISCUSSION... Drier conditions are expected to continue today with a slight warming trend. The winds will remain gentle to moderate with a few higher gusts. However, due to recent rains, soils are wet, and the criteria for fire danger are not met. KBDI values are all below 100 except in Cotton value which has 724. (However the 10 hr fuel moisture there is 25--the wettest of all). Guanica has begun to see some drying of fuels where the 10 hour moisture fell to 15 percent--still well above critical levels. Therefore, the risk of dangerous fire behavior is low today. The outlook is for increasing moisture on Friday which will continue through much of next week with a few exceptions.
