HAWAII ISLAND: High surf and heavy rainfall is heading for Hawaii Island this weekend, warns state emergency officials. A media release was issued this afternoon.
“National Weather Service (NWS) briefed Hawaii Emergency Management Agency (HI-EMA) this afternoon, along with federal, state, and local emergency management partners about multiple weather systems in the Central Pacific likely to impact the state over the weekend and into the week ahead.”Hawaii Emergency Management Agency on Oct. 2, 2015
Forecasters say breezy trade winds will continue into next week as Hawaii “is currently between high pressure to the north and two tropical disturbances to the south.”
“A relatively dry and stable airmass will give way to a deep trough aloft with increasing tropical moisture from the south may combine to produce an extended period of wet weather from late in the day Saturday into next week for the eastern half of the state.” National Weather Service on Oct. 2, 2015
“An area of moisture located to the west-southwest of Hawaii Island is expected to bring heavy rainfall beginning Saturday evening and lasting through Sunday. Hawaii Island and Maui County will feel the majority of the effects, while Oahu and Kauai are not likely to see much rainfall from this particular event.”Hawaii Emergency Management Agency on Oct. 2, 2015
Also, all islands will experience high surf due to a north-northeast swell, with 10–20 foot surf on north-facing shores and 5–10 foot surf on east-facing shores, the state says. A High Surf Advisory is in effect.
“Expect strong breaking waves, shore break, and strong longshore and rip currents making swimming difficult and dangerous. Beachgoers, swimmers and surfers should heed advice from ocean safety officials and exercise caution.” National Weather Service on Oct. 2, 2015
Officials are also monitoring two tropical disturbances below the state, TD 98-C and TD 97-C.
“TD 98-C is likely to drift west-northwest and cross into the Western Pacific early next week with no threat to the islands. However, TD 97-C is located 500 miles south of Hilo in an area where conditions are favorable for system organization over the weekend.
Forecasters warn of high uncertainty at this stage, but models show TD 97-C moving slowly to the north-northwest until Monday, and then curving sharply toward the east on Tuesday. This expected change in track will route the system on a northeasterly path toward the state. There is potential for heavy rainfall and high surf, but it is too early to predict the extent of those effects.”Hawaii Emergency Management Agency on Oct. 2, 2015
