Tropical Storm Hernan forms in the Pacific while a different weather system could soak Hawaii

Tropical Storm Hernan formed in the Pacific Ocean west of Mexico's Baja California peninsula and was not threatening land. Meanwhile, potential Tropical Cyclone One-C is near Hawaii and is forecast to bring heavy rain, high winds, and dangerous surf starting late Friday. This system could make landfall on the southern part of the Big Island as a tropical storm, potentially producing rainfall that leads to flooding.
