Former Hurricane Daniel has moved past the Hawaiian islands with minimal effect on the weather, and Tropical Storm Emilia, expected to reach the islands on Wednesday, isn’t expected to have much of an impact, either.
A high-surf advisory for Hawaii expired Saturday at noon as surf generated by the storm died down.
The low-pressure system caused only a slight increase in tradewinds and a little extra moisture to windward and mauka areas.
The remnants of Daniel moved west of the island and by Saturday morning were about 475 miles south-southwest of Lihue.
Emilia is following a similar path to Daniel and was expected to enter the Central Pacific Hurricane Zone, about 1,000 miles from Hawaii, today.
Forecasters expect Emilia to weaken to a tropical depression and then a remnant by the time it reaches the islands in midweek.
NASA’s Aqua satellite measured temperatures in Emilia’s clouds on Thursday and noticed a warming trend. That’s a signal that the storm doesn’t have as much power or "uplift" and is weakening, according to the NASA Jet Propulsion Laboratory in Pasadena, Calif.
The Atmospheric Infrared Sounder instrument aboard the Aqua satellite captured a look at Emilia’s cloud-top temperatures on Thursday, when the storm was still about 1,500 miles east of Hawaii.
As Emilia continues westward, wind shear is expected to take its toll on the storm, and according to the National Hurricane Center, it could be a remnant low as early as today.
Tradewinds are expected to continue into this week, delivering passing clouds and brief showers to windward and mountain areas. A slight increase in trade showers is possible on Monday.
Leeward areas are expected to experience continued dry conditions.
