During the course of Friday, a tropical storm with the potential to develop into a hurricane will be located off the coast of Colima, causing heavy rains in the west and south Mexico, with intense punctual rains in Michoacán, as well as strong gusts of wind and high waves on the coasts of Jalisco, Colima, and Michoacán.
On Saturday, the tropical storm (or possible hurricane) will be located off the coast of Jalisco and will move with a possible trajectory towards Nayarit or Sinaloa, causing very heavy rains in Nayarit and intense rains in Jalisco, Colima, and Michoacán.
If the forecast holds, the system could develop into a named storm on Thursday, taking the name Roslyn.
The hurricane season officially began on May 15 in the Eastern Pacific, and will end on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.
