Updated: Oct 3, 2023

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


North Atlantic

  • Tropical storm Philippe is struggling against moderate wind shear and is maintaining its intensity at 50 mph (85 km/h). 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.
