258 FNCA52 TJSJ 260816 FWFSJU Fire Weather Planning Forecast for Puerto Rico National Weather Service San Juan PR 416 AM AST Fri Jul 26 2024 .DISCUSSION... Similar conditions to yesterday are expected today across Puerto Rico, Vieques and Culebra. A strong Saharan Air Layer will continue to promote drier air and hazy skies across the local area. Breezy conditions are possible across the western coastal areas due to the stronger sea breeze, and wind speeds should range between 14-22 mph with higher gusts. Relative humidities should drop once again into the low 50% along the southern coastal areas of Puerto Rico. However, the KBDI remains below critical fire weather thresholds.
