Lots of sunshine and just a few light showers windward and mauka are expected for Monday, along with somewhat lighter trade winds. Those winds may be light enough to allow for some afternoon clouds and maybe a pop-up shower or two, especially for the Kona side of Hawaii island. The chance of showers will increase Tuesday due to moisture from the remnants of former tropical cyclone Agatha, while the light trades rebound.
Remnants of former hurricane Blas will lower trade wind speeds Wednesday night, and then bring more showers Thursday night into Friday. Meanwhile, we're keeping a close watch on Hurricane Celia, about 2,000 miles east of the Big Island. It's still too soon to say exactly what, if anything, we'll get from this cyclone, but any effects are still a week away.
At the beach, a long-period swell from Blas will diminish, but surf will remain a bit elevated for east shores. Waves on south and west shores are headed downward for now. There are no marine warnings or advisories in effect.
