• The 11th tropical storm in the Pacific this season is Kay.
  • It will likely impact Baja California by late week.
  • The system is forecast to become a Category 2 hurricane.

The National Hurricane Center officially named Tropical Storm Kay as of 5 p.m. Sunday. The system is currently swirling south of Mexico in the eastern Pacific Ocean.

It is forecast to impact Baja California later this week and could bring heavy rainfall along Mexico’s southwestern coast.



The system is expected to continue to swirl south of Mexico before eventually turning northward later this week.

Low to moderate shear and warm sea surface temperatures means the system will likely continue to strengthen through midweek. As it approaches Baja California and cooler sea temperatures, it could weaken slightly — though it is still forecast to approach Baja as a hurricane.

Although the system is forecast to remain offshore along the southwestern coast of Mexico, the outer bands could still bring heavy rainfall and localized flash flooding.
