A new tropical disturbance is now active in the South Pacific Ocean (being referred to as Invest 98P), circled in orange above. This tropical disturbance was located approximately 405 miles south-southeast of Pago Pago, American Samoa…according to the Joint Typhoon Warning Center (JTWC)

Satellite imagery shows a well defined low level circulation center, with persistent central convection, and broken convective cloud banding along the southern semi-circle. At the same time, there’s a broad circulation with a small area of sheared deep convection to the northwest of the center.

According to the JTWC, upper level analysis shows a poor environment, as an upper level low pressure system is positioned over the low level center. Meanwhile, moderate 15-25 knot (17-29 mph) vertical wind shear continues to act upon this system.

Estimated maximum sustained surface wind speeds were 25-30 knots (29-35 mph).

The JTWC is giving this disturbance a medium chance of developing into a tropical cyclone within the next 24 hours

Here’s a NOAA satellite image of this area.
