Tropical storm Cosme is reportedly gaining strength in the Pacific, where it is being declared a hurricane.

The storm is expected to show its full force today and weaken a bit each day throughout the week. Heavy winds could reach up to 75 MPH today.

Cosme is about 375 miles south of Mexico but is moving northwest, meaning dangerous swells and riptides for California later this week. You can track weather updates here. However, it’s not expected to get close enough to the coast to cause any damage on land.

There have been five previous storms named Cosme, dating back to 1983. Three of those were hurricane-force, and in 1989 Cosme hit Acapulco, killing 30 people with flooding waters.
