A Short Term Forecast has been issued by the National Weather Service for Maui County. A band of heavy showers is expected to move across the island of Maui between 5:30 p.m. and 7:00 p.m. this evening. Rainfall rates may briefly exceed 1 inch per hour. Motorists should expect reduced visibility as the heavy showers blow through. Meanwhile, a cold front currently over the Kaiwi channel is expected to move over Maui County this evening bringing a surge of strong gusty north winds and a few showers as well.

Marine Weather Statement has been issued by the National Weather Service. A cold front has entered the Kauai coastal waters and will move into the coastal waters around Maui County and then to the Big Island later today and tonight. The front will bring a distinct shift and increase in winds from westerly to northwesterly. Along the front and after it passes winds will increase to 20 to 30 knots and become northwesterly. Winds could gust as high as 45 knots with seas becoming rough and steep at 7 to 13 feet. Well out ahead of the front scattered brief heavy showers with strong gusty winds are moving from southwest to northeast across the waters. Isolated thunderstorms and lightning are another possibility.

A Small Craft Advisory is posted for all Maui County coastal waters (excluding  Māʻalaea Bay) from 6 a.m. Tuesday, Dec. 30, to 6 a.m. Wednesday, Dec. 31, 2014. Winds are expected out of the northeast from 20 to 30 knots with higher gusts with rough seas rising to 8 to 14 feet.

Looking Ahead

A cold front will sweep down the island chain today bringing stronger winds and showers, along with the possibility for a few thunderstorms. The front will reach Kauai around midday today, Oahu later this afternoon, Maui county early this evening, and the Big Island tonight. A brief period of rather dry northerly flow is expected New Year’s Eve and into New Year’s morning with decreased wind speeds. Thursday night through Saturday models are indicating a chance of thunderstorms. Uncertainty is still quite high so I will continue to watch this feature and bring you the latest as the forecast becomes more certain.
