However, there’s a tropical disturbance being referred to as Invest 93P…which is located approximately 87 NM east-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 indicate the associated deep flaring convection is displaced north-northeast of an ill-defined low level circulation.

Surface observations from Pago Pago reported winds less than 10 knots over the past several hours, along with a minor pressure decrease over the past 24 hours.

Although excellent outflow exists north-northeast of the system, upper level analysis indicates a marginally unfavorable environment, with diffluent winds directly overhead. However, an approaching trough of low pressure from the west, is causing subsidence…and moderately strong 20-25 knot wind shear.

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 is low.
