Honolulu’s weather forecast for today paints a picture of a potentially quite wet and unstable environment, according to the National Weather Service (NWS) in Honolulu. The region is under the influence of a “moist unstable airmass” that’s expected to persist through the day. Light winds will give way to sea breezes this afternoon, which could lead to locally heavy showers and a couple of thunderstorms.

This could mean areas east of Kauai may see heavier showers and potential thunderstorms as the day progresses. Residents and visitors should anticipate the possibility of brief periods of reduced visibility and necessary changes to travel or leisure plans.
