Category 4 Hurricane Lane will impact Hawaii the rest of this week

Very dangerous Hurricane Lane is currently centered around 210 miles south-southwest of Kona on the west side of the Big Island of Hawaii and is moving northwest at 7 mph. The maximum sustained winds are at 130 mph, making Lane a Category 4 hurricane.

Lane should remain a major hurricane through at least today and tonight. A combination of increasing wind shear and gradually lower ocean heat content will cause the powerful hurricane to slowly weaken through the rest of the week. Despite the weakening, Lane has the potential to unleash damaging winds and torrential rainfall over most islands.

A hurricane warning is in effect for the Big Island of Hawaii, Oahu and Maui County including the islands of Maui, Lanai, Molokai and Kahoolawe. A hurricane watch is in effect for the islands of Kauai and Niihau.

Lane is moving on a northwesterly course. As anticipated, high pressure to the north steering the hurricane has started to weaken. The powerful hurricane will continue to track toward the northwest through today then on a more north-northwesterly course tonight into tomorrow. The core circulation and the main cloud shield around the hurricane is now passing southwest of the Big Island of Hawaii.

However, bands of clouds forming east and north of the main circulation are already bringing gusty winds and showery rainfall over south and east sections of the Big Island, and this will continue through tonight. The more northwesterly movement of Lane will bring the center of the hurricane to within about 80 miles of the west coast later today and tonight.

Tropical storm-force winds, greater than 39 mph, and heavier and perhaps flooding rainfall will impact western sections of the Big Island today into tomorrow and perhaps into Saturday. These winds and heavier rainfall should also impact the islands of Maui, Lanai, Molokai and Kahoolawe starting tonight then start to impact the islands of Oahu and Kauai tomorrow. These impacts will continue over most islands into Saturday.

Large swells generated by Lane will create rough and dangerous surf, mostly over south- and east-facing coastal areas of the Big Island today. There will then be an increase in surf over all Hawaiian Islands tonight into tomorrow. That increase in surf will start to impact all of the islands as Lane eventually moves on a more north-northwesterly course.

These swells will bring rough and more dangerous surf to mostly south and some west-facing coastal areas through the weekend.

There is the potential for Lane to bring not only severe damage to some of the islands but also bring life-threatening conditions. All residents, visitors and interests on the Hawaiian Islands should closely monitor the movement of Hurricane Lane. Local officials will advise on potential evacuations and other suggested preparations.

Future tropical development is not expected across the rest of the Central and all of the Eastern Pacific Basin through at least early next week.

Western Pacific:

Soulik over South Korea; Cimaron crosses Japan

As of Thursday afternoon, EDT, the center of Severe Tropical Storm Soulik was over South Korea about 195 miles south of Seoul. Soulik is moving to the north-northeast at about 9 mph. Highest sustained winds are 70 mph with gusts to 95 mph.

Soulik is expected to weaken as it moves across South Korea during the next 12 hours. Friday and Saturday, Soulik will continue to weaken as it accelerates toward the northeast over the Sea of Japan, or East Sea, ultimately passing near northernmost Japan and southern Sakhalin Island. The northern Japanese island of Hokkaido may get a shot of heavy rain this weekend.

Previously, Soulik struck Jeju with torrential rains and severe winds, with a peak gust near 65 mph being reported. Wind-swept heavy rain has begun to spread into the southern mainland of Korea and will continue to spread over much of South Korea as Soulik crosses the peninsula.

Meanwhile, Typhoon Cimaron is centered about 80 miles north-northwest of Osaka, Japan. Cimaron is tracking toward the north at 27 mph with highest sustained winds near 75 mph.

Typhoon Cimaron made landfall in southwestern Japan late on Thursday, local time, in eastern Shikoku. Cimaron has since crossed Honshu and emerged into the Sea of Japan. Damaging wind gusts and torrential rainfall have impacts portions of central Honshu. Though it will be weakening, Cimaron will still be a significant tropical storm as it crosses Hokkaido shortly before Soulik.

Also, developing tropical low pressure is centered over southern Taiwan. This low has potential to consolidate into a tropical depression within 12-24 hours. Excessive rainfall is already falling in southern Taiwan with some areas receiving 20 inches on Thursday alone. Rounds of heavy rain should continue through the weekend.
