However,  there’s a tropical disturbance being referred to as Invest 95W…located approximately 261 NM east-southeast of Ho Chi Minh City, Vietnam

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

Here’s a looping satellite image of this system

According to the Joint Typhoon Warning Center (JTWC), satellite images shows flaring deep convection and low level clouds wrapping into the covered low level circulation center.

Upper level analysis indicates a fair environment for development with strengthening divergence aloft.

95W is located in an area of low 5-10 knot wind shear…along with warm sea surface temperatures.

Global models show the circulation persisting and moving westward, then potentially developing in the Bay of Bengal…west of the Malay Peninsula.

Maximum sustained winds are estimated to be 17-23 knots.

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

Maximum sustained winds are estimated to be 18-23 knots.

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

>>> Finally,  there’s a tropical disturbance being referred to as Invest 99B…located approximately 168 NM northeast of Colombo, Sri Lanka

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

Here’s a looping satellite image of this system

According to the Joint Typhoon Warning Center (JTWC), satellite images shows flaring convection associated with a broad low level circulation.

Upper level analysis indicates a favorable environment for development with strong divergence aloft…and some poleward outflow.

99B is located in an area of low 5-10 knot wind shear…along with warm sea surface temperatures immediately to the north.

However, land interaction with Sri Lanka and the Indian subcontinent is currently unfavorable for the disturbance.

Global models show the circulation persisting, although depict it falling apart or only weakly intensifying surface winds in 4-5 days…drifting slowly westward into the central Bay of Bengal.

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 low
