Looking Ahead

Former Tropical Cyclone Greg is forecast to bring increased showers and humidity through tonight. Some of those showers could be heavy at times. The leeward Big Island slopes will see a few afternoon downpours over the next couple of days. A drying trend is expected Saturday into Saturday night. Moderate trade wind speeds are forecast for the next week.

Today 

We expect trade winds around 15 mph. High temperatures are forecast from 81° to 86° and feeling warmer due to the high humidity levels. Mostly cloudy skies with showers likely for the Hilo side. For the Kona side, partly sunny morning and showers likely in the afternoon. Locally heavy rainfall possible.
