The remnants of Fernanda will move east to west across Oʻahu and Kauaʻi today, bringing with it the threat of heavy showers and thunderstorms to those islands, and mugginess to Hawai‘i Island and Maui.

But more storms are brewing in the Eastern Pacific.

Three tropical cyclones from west to east are Tropical Storm Greg, Tropical
Storm Irwin and Hurricane Hilary.

So far in July, five named storms have developed in the area.
