However, there’s a tropical disturbance being referred to as Invest 93P…which is located approximately 140 NM south-southeast of Pago Pago, American Samoa

Here’s a NOAA satellite image of 93P, along with what the computer models are showing.

Here’s a near real-time wind profile of this area in the South Pacific.

According to the Joint Typhoon Warning Center (JTWC), satellite images show an elongated low level circulation center, with deep flaring convection along the eastern semi-circle.

Upper level analysis indicates a marginally favorable environment, with good outflow offset by moderate to strong 15-20 knot wind shear.

Weather models show weak development of the system over the next few days, as it tracks southward.

Maximum sustained winds are estimated to be 20-25 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours remains low.
