Flood Watch Still Posted, Muggy Conditions Continue
Alerts
A Flood Watch remains in effect until 6 p.m. Tuesday for all islands. An unstable and very moist air mass on the back side of the tropical system is lingering across the state. This moisture interacting with the land is expected to produce periods of heavy rain and slow-moving downpours that could lead to flash flooding. If that occurs a more urgent Flood Advisory (flooding is imminent) or Flood Warning (flooding is occurring) will be posted by the National Weather Service.

Looking Ahead
Extremely humid conditions will keep showers heavier than usual over the islands through most of the week. Light winds will yield to modest trade winds by the weekend, and they may start to bring in drier air, but unsettled conditions appear likely to return by early next week.
Today
It’s going to be another extremely muggy day. Today we expect partly to mostly cloudy skies. Scattered showers, thunderstorms and locally heavy rainfall are possible. High temperatures from 83° to 88° are expected but will likely feel warmer than the thermometer indicates. Variable winds from 5 to 15 mph are forecasted.
UV index at 13 (“extreme” exposure level)
Tonight
Light and variable winds are expected this evening. Humidity will soar again with low temperatures from 73° to 79° but feeling much warmer. Partly to mostly cloudy skies are expected with scattered showers and locally heavy rainfall possible.
