Forecasters say a weak disturbance moving into the eastern half of the state today will bring an increase in showers, and possibly a few thunderstorms for Hawaii County.
At the same time, a stalled cold front north of the Hawaiian islands will diminish the normal tradewind flow. Light and variable trades are expected through Friday.
An earlier flood advisory for Hawaii island was canceled at 9:47 a.m. today.
Today’s forecast includes isolated to scattered, afternoon showers, and highs from 89 to 94 degrees Fahrenheit. Tonight’s lows range from 69 to 74 degrees. Variable winds of 5 to 15 mph are expected through tonight, with no change until this weekend.
On the surf front, a new north-northwest swell is expected to arrive tonight, bringing surf near advisory levels for the north shores of the smaller islands, as well as the west shores of Kauai.
Surf for north shores at 8 to 12 feet this evening is expected to reach 10 to feet on Friday. Surf on west shores is expected to remain at 4 to 6 feet this evening through Friday. East facing shores will remain steady at 2 to 4 feet through Friday. South facing shores remain flat, at 0 to 2 feet this evening through Friday.
The new north-northwest swell will gradually lower Friday night through early next week.
Then on Sunday, a long-period, east swell associated with an east Pacific tropical cyclone is expected to boost surf along east shores Sunday night through early next week. Surf is expected to peak at advisory levels.
Trades, meanwhile begin to return over the eastern isles on Saturday, with moderate trades spreading statewide, starting Sunday.
Clouds and brief showers will shift back to typical windward and mountain areas as the tradewinds return.
