Hello everyone! Here is the tropics outlook for October 2 which covers the Northern Hemisphere.

However, the system is making its closest approach to the Leeward Islands, with heavy rainfall remaining the primary threat. Tropical storm watches are in effect for Antigua & Barbuda.

Eastern Pacific

• Invest 98E is quickly organizing and has a 90% chance of developing into a tropical depression within the next 2 days. Impacts on any land remain uncertain.

• An area of interest was marked south of Oaxaca, Mexico, and has a 60% chance of forming into a tropical depression within the next 7 days.

Western Pacific

• Typhoon Koinu continues to rapidly intensify and is now a high-end Category 3 typhoon with sustained winds of 125 mph (200 km/h). The typhoon is heading northwest as shear increases and will impact southern Taiwan in about 2 days. Preparations should be underway for Taiwan.
