UV index at 13 (“extreme” exposure level)
For leeward areas, partly cloudy skies are expected tonight with clearing as the night goes on. Windward spots are mostly cloudy and showers are likely. Northeast winds are forecasted from 15 to 20 mph. Low temperatures from 73° to 78° are expected.
Locally breezy trade winds are expected through the weekend. The trades will bring some showers to windward areas, mostly during nights and mornings. Remnant moisture from a former tropical depression (Eight-E) will reach us this weekend, bringing muggy weather and increased showers for windward areas, especially for the Big Island.
Hurricane Guillermo Update
The National Hurricane Center in Miami is issuing bulletins on Hurricane Guillermo, which is a little less than 2000 miles east-southeast of Hilo. The current forecast is for Guillermo to move west-northwest and strengthen, potentially crossing into the Central Pacific Hurricane Center area of responsibility on Saturday. Impacts to Hawaii will be very dependent upon the track and speed of the system, which is highly uncertain this far out in time. I will keep an eye on this system and begin doing regular updates when the system gets a little closer to the islands.
