Rain clouds pulled over the islands by the remnants of former Hurricane Jimena moved over Oahu and Hawaii island Sunday morning, bringing cloudy skies and scattered showers.
"There’s a lot of moisture out there," said Matt Foster, a meteorologist with the Honolulu office of the National Weather Service. "The tradewinds haven’t really picked up yet."
"Radar shows an active area of heavy showers migrating to the west northwest across over waters just south of Oahu and Maui county. Light, but steady incoming showers are observed over the windward and southeast portion of the Big Island this morning," forecasters said late Sunday morning.
"Expect clouds and showers, along with muggy conditions to linger on and off through the day, then begin to taper off tonight," forecasters said in an advisory.
Foster expects the southeast winds bringing the rain to gradually shift to easterly, then northeasterly winds overnight into Monday.
That should bring some relief from the oppressive humidity of the last few weeks, although temperatures will still be hot.
The National Weather Service lifted a flash flood watch for Oahu and Kauai Sunday morning and a flood advisory for Hawaii island overnight.
In the 24-hour period ending at 5 a.m., 2.4 inches of rain fell in the Saddle Quarry and 1.8 inches fell at the Hilo Airport. On Oahu, a little less than 1.2 inches fell at the Oahu Forest National Wildlife Reserve in the northern Koolau mountains.
The weather was wet, but still drier than Friday, when a record rainfall of 1.36 inches for the date was recorded at the Honolulu Airport. The old record was set in 1992, when Hurricane Iniki passed west of Oahu.
The forecast for most of the state Sunday calls for partly sunny skies with scattered showers and highs between 87 and 92 degrees.
Sunday night and Monday morning should be partly to mostly cloudy with scattered windward and mauka showers and isolated showers in leeward areas.
Tradewinds should keep blowing over the islands until the weekend, when another weather system may bring a return of muggy weather and showers.
