HAWAII - Hurricane Olivia moved from the Eastern Pacific into the Central Pacific and is expected to affect Hawaii. NASA’s Aqua satellite the northeast and southwestern quadrants of the storm to be the most powerful on Sept. 10.
Infrared satellite data on Monday from the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite revealed the strongest storms were southwest and northeast of the center. In those areas MODIS found coldest cloud tops had temperatures near minus 70 degrees Fahrenheit. NASA research has found that cloud top temperatures that are cold have the capability to generate heavy rainfall.
The MODIS data showed that the strongest storms only extended out 30 miles from the center. Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 115 miles.
The Central Pacific Hurricane Center of CPHC noted a Tropical Storm Warning is in effect for Hawaii that covers Maui County, including the islands of Maui, Molokai, Lanai, and Kahoolawe and Hawaii County. A Tropical Storm Watch is in effect for Oahu.
Maximum sustained winds are near 85 mph with higher gusts. Little change in strength is forecast today, with slight weakening starting tonight and continuing through Tuesday. However, Olivia is forecast to be a strong tropical storm when it reaches the Hawaiian Islands.
On this forecast track, tropical storm conditions are expected over parts of Hawaii starting late Tuesday.
