Hawaii has been enduring unusually hot and humid weather lately.
Vanessa Almanza, a meteorologist with the National Weather Service in Honolulu, said today’s humidity was caused by a surface trough to the northwest of the islands drawing moisture over the state from the south.
This weekend’s humidity, however, was caused by a different system. Almanza said that was from the remnants of Tropical Storm Kristy in the Eastern Pacific sending moisture over the islands via the trade winds.
