Two potential typhoons are brewing in the Northwest Pacific Ocean, with the first typhoon of 2024 likely to emerge soon, following four months of calm cyclone conditions.

One of the embryonic formations, Typhoon Embryo 90W, is currently positioned at approximately 5.0 degrees north latitude and 143.0 degrees east longitude, boasting maximum wind speeds of 15 knots and a central minimum pressure of 1007 hectopascals.
Another formation, Typhoon Embryo 91W, resides around 3.2 degrees north latitude and 136.9 degrees east longitude, with maximum wind speeds of 20 knots and a central minimum pressure of 1008 hectopascals.
The Global Forecast System (GFS) from the United States expresses concern about Typhoon Embryo 91W’s potential development, suggesting it may form over the upcoming weekend, possibly tracking toward the Philippines before veering northward toward Japan. However, due to its location in low-latitude waters near the equatorial region, its development rate is anticipated to be slow.
Both GFS and the European Centre for Medium-Range Weather Forecasts (ECMWF) largely agree on the trajectory of Typhoon Embryo 91W. However, whether it will evolve into the first typhoon of 2024, potentially named “Aiyuni,” remains highly uncertain and requires continued monitoring.
