Tropical Cyclone Activity Report – Pacific Ocean / Indian Ocean / Arabian Sea

There are no active tropical cyclones at the time of this writing

 

PDC Disaster Alert, displaying PDC Active Hazards, 3-hour precipitation accumulations…with a tropical disturbance that has a low chance of developing

However, there’s a tropical disturbance which is being referred to as Invest 90S…located approximately 915 NM east of Diego Garcia…in the South Indian Ocean

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

According to the Joint Typhoon Warning Center (JTWC), satellite images depict an area of flaring convection to the southwest of a developing low level circulation center.

The upper level environment is currently marginal with weak upper level divergence, and 20-25 knots of wind shear. Meanwhile, sea surface temperatures in the area are favorably warm.

Global models track this system in a southwestward direction, and indicates steady development over the next few days.

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

 

Eastern North Pacific

There are no current tropical cyclones

1.) An area of low pressure is expected to form just off the west-central coast of Mexico late this week in association with the remnants of Atlantic Tropical Storm Franklin after it moves across southern Mexico. Some development of this system is possible this weekend before it moves west-northwestward into less conducive environmental conditions.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…low…30 percent

2.) Another area of low pressure is forecast to form well south of the coast of southern Mexico late this week. Environmental conditions are expected to be conducive for some gradual development of this system over the weekend and early next week.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…low…30 percent
