Another hot and muggy day with scattered showers is expected Friday as a weather system moving over the state brings rain clouds and humidity to the islands through the weekend.

Rain, falling at a rated of 1.5 inches per hour, prompted a flood advisory for the south shore of Kauai at 6 a.m. Friday morning.

The National Weather Service lifted the advisory at about 8 a.m. when the rain moved offshore.

Moderate tradewinds should help cool things off Friday, but the tradewinds may weaken on Saturday and Sunday and forecasters say there’s a possibility of humid, Kona winds on Tuesday.

The rains through the weekend will be mostly in windward and mauka areas, but some showers may be blown over the mountains to leeward areas.

Tradewinds will be light to moderate Friday, blowing at 15 to 20 mph with higher gusts.

Record temperatures continued Thursday when Hilo set a new high of 90 degrees, breaking the old record of 87 for the date set in 2003. It was the second day in a row of record temperatures at the Hilo Airport and the sixth day of record temperatures at the airport since Sept. 17.

Record highs have been recorded in Hawaii for the last 9 days straight.

Hilo and Lihue tied high temperature records Wednesday. The high of 89 degrees at Hilo tied a record for the date set in 2005.

Lihue’s high of 87 degrees tied a record set last year. It was the second straight day of record temperatures on Kauai.

On Tuesday, Maui saw its third straight day of record temperatures with a 92 degree high tying a record at Kahului Airport set in 1993.

Temperatures are expected to cool off a little on Friday, with highs between 83 and 88.
