After becoming a hurricane last Friday, Vance has weakened to a tropical storm. It's moved far enough away from the Mexican coast to take most of the winds, but some rain continues to graze some parts of the coastline. Its slow movement will mean long-lasting coastal wave action and erosion potential. The good news is, it should weaken as it enters an unfavorable environment early this week. A landfall in Mexico late this week is possible.

Tropical Storm Olana formed in the Central Pacific Ocean this week but has since become post-tropical. This storm is west of the Hawaiian Islands. Hawaii can see multiple inches of rain from the moisture from Olana through Saturday. Here's the latest forecast from our Global American model.

El Niño Fueling Pacific Activity

The Eastern Pacific has set a new record for the most energetic season since record-keeping began. The ACE has surpassed 318, which was the previous record set in 2018.

The surge in tropical activity comes as El Nino continues to strengthen across the equatorial Pacific. El Nino is characterized by warmer-than-average ocean temperatures across portions of the central and eastern equatorial Pacific. Those unusually warm waters can influence weather patterns around the globe while also creating an environment that can favor tropical cyclone activity in the Pacific.

This year’s El Nino has already strengthened considerably, and forecasts indicate it could become exceptionally strong later this year.
