HONOLULU (HawaiiNewsNow) -

Things are heating up in Honolulu where meteorologists say the heat index reached a sweltering 100 degrees on Thursday. 

The heat index is how hot it feels outside when accounting for the actual temperature coupled with the humidity in the air. And around 11:23 a.m., the index spiked to triple digits.

While the hot weather is largely due to it being summer, National Weather Service officials say Hurricane Hector lent a helping hand.

"With the hurricane that passed us, it brought some increased moisture into the area," said Gavin Shigesato, a meteorologist with the National Weather Service. "The moisture that was moving in behind Hector is currently moving through the islands."

High humidity and temperatures in the high 80s and low 90s kept the heat index high on Thursday, dropping to around 94 degrees a few minutes before 4 p.m.

Hot and humid weather is expected to persist throughout the state with partly-sunny skies on Friday.
