In East Hawaii, the forecast for a wet weekend did not materialize and record heat temperatures were recorded.
Meanwhile, in the Eastern Pacific, Hurricane Kiko has become a Category 2 hurricane over the weekend, contrary to forecasts that had weakened it into a tropical storm.
On Friday, despite a dark, rainy afternoon, the National Weather Service recorded a high temperature of 88 degrees at the Hilo International Airport, matching the record set in 2013.
And on a stifling Sunday, mercury reached 90 degrees at Hilo, matching the previous record set in 1972.
At 11 o'clock today, the center of Hurricane Kiko was 2,035 km east of Hilo. Maximum sustained winds are 100 mph with locally higher gusts.
The storm is relatively small and moves slowly but is heading west at 5 mph. Hurricane winds extend outward for up to 15 miles from the
Central winds and tropical storms extend outward to 100 km from the center.
Forecasters at the National Hurricane Center in Miami predict that the storm will head west-southwest Tuesday, and then turn west on Wednesday. This motion will continue until Thursday.
Weather observers say the storm is slowly weakening and predict that this trend will continue over the next two days. So little change in the force is expected Thursday.
Forecasters are also considering two disturbances off the coast of Mexico, which they predict may turn into tropical cyclones.
The first is a small low pressure zone centered several hundred kilometers south-southwest of Manzanillo, Mexico, which forecasters have begun to organize.
"Any significant increase in organized storm activity will likely result in the formation of a tropical depression tonight or (Tuesday)," the forecast predicts.
The chances of this disturbance becoming a tropical cyclone in the next 48 hours are estimated at 80%.
A second zone of stormy activity associated with a larger low-pressure zone is closer to Mexico's southwestern coast and is also becoming better organized, forecasters say. His chances of becoming a tropical cyclone are even greater, with forecasters predicting a 90% probability of organization within 48 hours.
Closer to home, forecasters at the Central Pacific Hurricane Center in Honolulu are monitoring three disturbances, but two are located southwest of Hawaii and are unlikely to affect the island's climate.
The third, described as "an extended low pressure zone", is about 800 miles southeast of Big Island.
"Slow development is possible over the next few days, while the area is slowly moving west," the forecast says.
Forecasters say the chances of tropical cyclone formation are low – almost nil in the next 48 hours and about 20% over the next five days.
