The Joint Typhoon Warning Center (JTWC) forecasts that both depressions 92W and 93W are creating a large area of unorganized showers and thunderstorms. Upper-level winds are not particularly favorable for development, but these two systems have a short chance of becoming tropical depressions in the short term as they will remain in the area for the next few days. The JTWC assessed the chance of these two low pressure systems strengthening over the next 7 days at 30%.
According to Windy.com, at 7:00 a.m. on September 24, the center of low pressure 93W was at about 21.39 degrees north latitude, 110.18 degrees east longitude, central pressure 1,008hPa, 265.2km from Co To Island, Vietnam.
The JTWC is also monitoring a system called Area B northeast of Luzon Island, Philippines, with the possibility of a new low pressure area forming later this week. The low pressure develops as it moves slowly and erratically westward, and could become a tropical depression on September 29 as it approaches the Luzon Strait. The chance of formation within 7 days is 40%.
In addition, in the area east of Guam and Rota, the weak depression Invest 91W is causing showers. Upper-level winds are not favorable for development and the possibility of significant development of this system is very low as it moves west-northwest in the next few days. The 7-day chance of development is only 10%.
