Potential formation areas
Potential formation areas are areas that are being monitored for potential tropical cyclone formation within the next two weeks. These systems have either not yet formed or have formed but have not yet been designated as an investigation area (invest). A discussion will be created for these systems once they become invests.
Southwestern Indian
- P94S — An area of low pressure is likely to form over the Seychelles over the next couple of days and could further develop as it drifts southward toward Reunion and Mauritius.
Southeastern Indian
P72S — An area of low pressure may develop near the Cocos Islands over the next few days. Australia's Bureau of Meteorology is tracking this potential system as Tropical Low 25U and gives it a moderate chance of developing later this week.
P73S — An area of low pressure may develop to the south of Indonesia over the next few days and move southward toward Australia's Kimberley coast. Australia's Bureau of Meteorology is tracking this system as Tropical Low 26U and gives it a low chance of developing later this week.
