There’s a tropical disturbance being referred to as Invest 91P…which is located approximately 170 NM southwest of Bora-bora

According to the JTWC, satellite imagery depicts flaring convection along the east-northeast periphery of a weak low level circulation.

Environmental analysis reveals favorable conditions for development with robust equatorward outflow aloft, low to moderate (10-15 knot) vertical wind shear, and warm sea surface temperatures.

Global models are in general agreement that 91P will track west-southwestward and deepen over the next 24-48 hours.

Maximum sustained surface winds are estimated at 20 to 25 knots.

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