However, there’s a tropical disturbance being referred to as Invest 92W…which is located approximately 95 NM northwest of Palau

Here’s a satellite image of this disturbance, with a more expanded view…along with what the computer models are showing.

Here’s a near real-time wind profile of this disturbance

According to the Joint Typhoon Warning Center (JTWC), satellite images show a slowly consolidating low level circulation center, with persistent core convection.

Surface observations from Koror, Palau indicate that winds have shifted more southerly, indicative of a strengthening surface circulation.

Upper level conditions are marginally favorable, with low wind shear, and good poleward outflow.

Global models indicate limited development, although also show a west-northwestward track towards the central Philippines.

Maximum sustained winds are estimated to be 15-20 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.

Meanwhile, there’s a tropical disturbance being referred to as Invest 92B…which is located approximately 763 NM southwest of Yangon, Myanmar

Here’s a satellite image…along with what the computer models are showing.

According to the Joint Typhoon Warning Center (JTWC), satellite images show a consolidating low level circulation center, with flaring convection wrapping into the center.

The disturbance is currently located in a favorable environment, with sufficient upper level divergence, low 5-10 knot wind shear…and warm sea surface temperatures.

Global models are in agreement that the disturbance will continue to develop, and track northeast over the next 2-3 days.

Maximum sustained winds are estimated to be 10-15 knots.

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