811 FNCA62 TJSJ 290617 RFDSJU PRZ014-015-024>027-VIZ001-002-291830- Fire Danger Statement National Weather Service San Juan PR 217 AM AST Sat Aug 29 2026 ...ELEVATED FIRE WEATHER CONDITIONS EXPECTED TODAY ACROSS SOUTHERN PUERTO RICO, VIEQUES, CULEBRA, AND THE U.S. VIRGIN ISLANDS MAINLY FROM 10 AM TO 5 PM AST... A drier-than-normal air mass will move into the region by mid-morning today, replacing the moisture associated with a weak tropical wave. As a result, minimum relative humidity values are expected to fall into the mid-50s or lower across portions of the islands. Easterly winds of 12 to 18 mph are expected, with locally higher gusts, especially near coastal areas. These conditions, combined with dry fuels due to ongoing rainfall deficits, will increase the potential for wildfire ignition and rapid spread. Therefore, an elevated fire danger is expected today across portions of the southern plains and hills of Puerto Rico, as well as Vieques, Culebra, and the U.S. Virgin Islands. A Fire Danger Statement is in effect from 10 AM through 5 PM AST for these areas. Fire and emergency officials should be aware that weather conditions are becoming more conducive for the ignition and spread of wildfires. Fire danger statements are issued when fire weather conditions are approaching, but not meeting or exceeding, Red Flag Warning criteria. $$
