Northwest and Southwest Pacific Ocean, Indian Ocean, Arabian Sea:

There’s an area of disturbed weather, being referred to as Invest 90W which is located approximately 461 NM east of Iwo-To, Japan

According to the JTWC…Animated enhanced infrared satellite imagery depicts a northwest to southeast oriented open wave with deep convection in the eastern periphery.

Environmental analysis reveals favorable conditions for development defined by divergence aloft, low (5-10 knot) vertical wind shear and warm sea surface temperatures.

Global models have backed off on the development of 90W but are still in general agreement that it will track north-northwestward.

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 is upgraded to medium.
