Residents and visitors in Hawaii are being cautioned as fire weather concerns grow due to a blend of gusty trade winds, low humidity, and dry vegetation. According to the National Weather Service (NWS) in Honolulu, a Red Flag Warning has been issued for the leeward sections of all islands from this late morning through the afternoon. This warning flag comes as relative humidity values are expected to dip to alarming levels, creating conditions ripe for wildfires.
The strong trade winds in Hawaii are a bit weaker than yesterday, but drier air is still causing dangerous conditions. The Wind Advisory for the Big Island has been canceled because the winds have decreased. However, AIRMET Tango is still in effect, warning pilots about moderate turbulence that could disrupt air travel over and around the islands.
Water enthusiasts should note that strong trade winds from a high-pressure ridge north of the islands are impacting marine conditions. A Small Craft Advisory is in effect for several areas and will last until tonight. Conditions are expected to improve by Thursday night as the high-pressure ridge weakens.
Surfers should note that the High Surf Advisory for north-facing shores has been lifted, and north swell waves are declining. While the surf on west-facing shores may still be elevated due to wraparound energy, small south-shore surf will continue this week. A small long-period south swell is expected to arrive in Hawaii from Friday into Saturday.
As for general weather, the islands will experience brief clouds and showers primarily over windward areas while showers are set to increase tonight through Friday night due to a mid-level trough. This changing pattern, including the influence of an upper-level low and a weakening wind velocity by Thursday night, signals a gradual alleviation of the critical fire weather conditions. However, the public is still advised to stay cautious today during the elevated-risk period.
