Tropical Storm Lane is getting weaker, but there are still epic rainfall over Hawaii



Tropical Storm Lane continued a weakening trend overnight as the mountainous and rugged Hawaiian Islands ruptured the previous Category 5 hurricane.

Despite being downgraded to a tropical storm, Lane continues to produce catastrophic rainfall on the Big Island of Hawaii, where flash floods and landslides force numerous road closures, evacuations and rapid water rescue. At least four weather stations on the Big Island have reported more than 40 inches of rain since Wednesday afternoon.

And there is a lot more rain on the way. At the end of the weekend, Lane could become the wettest tropical system in the United States, breaking a record a year ago when Hurricane Harvey fell 60.58 inches of rain in Port Harvey, Texas.

Lane was downgraded to a tropical storm at 2:00 pm Hawaiian time (8:00 pm East) on Friday after the storm was quickly weakened when it encountered an unfavorable environment as the center of circulation neared the islands. At 11:00 am Eastern time on Saturday, Lane had maximum sustained winds of 60 mph and was about 110 miles southwest of Honolulu, moving north at 3 miles per hour.

Lane is likely to lose his tropical storm status in the next 36 hours. But the storm will continue to generate immense rainfall until the remainder of the weekend, with additional 10 to 30 inches of rain for parts of the Big Island.

The island of Oahu, home of Honolulu and 70 percent of Hawaii's 1.4 million people, have not yet experienced the same effects as the Big Island. In and around Honolulu, five to ten centimeters or more of rain is expected, most of which will fall in the next 36 hours.

Devastating Precipitation on the Big Island [19659010] Lane has produced some breathtaking rainfall with rainbands reinforced by sloping terrain on the east side of the Big Island, and Hilo, on the northeastern side of the Big Island, recorded 15 inches of rain on Friday, the fifth-wettest day since inception Hilo has received 31.85 inches of rain since Wednesday, representing the wettest three-day period that has been recorded. The combination of modified rainfall bands and a slow-moving storm system means that a lot more rain is likely to be fall on the Big Island. #Hawaii from #Lane is already extremely heavy rain & unfortunately there is much more.

The #HRRR threatens heavy rains most of the n / 36hrs. Supported by the training of convective bands and the rise of the current, the E-side of Hawaii can add 20-30 "rain! pic.twitter.com/5xC7mlFzRJ

Dramatic Destruction of Lane on Satellite

On Friday afternoon, satellite imagery captured a mesmerizing and rapid weakening of Lane as the Big Island storm approached. Tropical systems prefer windless wind patterns Wind Speed ​​or Direction with Altitude When Lane's outer bands alternated with land on Friday afternoon, the steep and steep slopes of the Hawaiian terrain created an area of ​​wind shear.

Lane's center of circulation was essentially split in two with a surface-based circulation center south of Hawaii and one in the opposite direction north As the flooding in the Big Island exemplifies, weakened tropical systems can still be dangerous.
