Overview

• The National Hurricane Center has raised the western disturbance’s chance of becoming a named storm to 80 percent and set the eastern system at 70 percent for the next seven days.
• Both disturbances are moving west-northwest and could affect coastal areas of southern Mexico or the U.S. Southwest by early next week.
• AccuWeather senior meteorologist John Feerick says the two systems could interact or even merge, though most forecast models predict they will strengthen separately.
• Record-warm sea surface temperatures and low wind shear have driven the season’s early activity since its May 15 start, nearly a month ahead of the climatological norm for the first storm.
• Forecasters project an above-average season in the Eastern Pacific with 14 to 18 tropical storms and seven to 10 hurricanes through November 30.
