Though Hawaii is known for its lush, tropical landscapes, the volcanic mountains, prevailing winds and ocean currents produce micro-climates throughout the island chain. Unfortunately, current atmospheric conditions set the stage for wildfires that are now raging in western Maui.
A dome of high pressure north of the archipelago and Hurricane Dora to the south are combining to rake the westernmost islands with strong east winds. Gusting to 60 mph or more, the intensity and drying effect of these winds is exacerbated by the mountainous terrain. As these winds descend west of the volcanos, the air heats up and dries out, augmenting the risk of wildfires.
Indeed, the current wildfires developed on the western slopes of the mountains, invading heavily-populated tourist areas. Though the winds are expected to subside through the day, damage is reported to be extensive. At least one wildfire has also developed on the west side of the Big Island.
