A broad area of low pressure located over 800 miles southwest of the southern tip of the Baja California peninsula continues to produce some disorganized shower activity. Environmental conditions are somewhat conducive for development, and a short-lived tropical depression could form by late this week while the low moves generally northwestward at 10 to 15 mph. This system is forecast to move over cooler waters and into a more stable environment by the weekend, which should inhibit further development.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 5 days…medium…50 percent

Central north Pacific

Northwest Pacific

There’s a tropical disturbance being referred to as Invest 99W…located approximately 382 NM east-southeast of Guam

Here’s what the computer models are showing

According to the JTWC, a discreet low-level circulation center has consolidated over the past 12 hours, with a small but well-defined circulation surrounded by 12-17 knot winds. A band of 20-25 knot winds extends from south to southeast of the center. Animated enhanced infrared imagery depicts flaring disorganized convection primarily on the south and east side of the rotation.

Environmental analysis indicates a favorable environment for development with a combination of strong outflow aloft with a point source or anticyclone aloft direction overhead the circulation, low (10 kt) wind shear and very warm  sea surface temperatures.

Maximum sustained surface winds are estimated at 18-23 knots.

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

>>> There’s a second tropical disturbance being referred to as Invest 90W…located approximately 168 NM northwest of Puerto Princesa

Here’s what the computer models are showing

According to the JTWC, maximum sustained surface winds are estimated at 15-20 knots.

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

South Indian Ocean

There’s a tropical disturbance being referred to as Invest 90S…located approximately 560 NM east-southeast of Diego Garcia

Here’s what the computer models are showing

According to the JTWC, satellite imagery depicts an exposed low level circulation center with flaring convection displaced to the south.

Environmental analysis reveals marginally unfavorable conditions with high (30-40 kt) wind shear, offset by pronounced radial outflow and high sea surface temperatures

Global models are in agreement that invest 90S will track to the southwest with the GFS deterministic model showing the most aggressive prediction.

Maximum sustained surface winds are estimated at 25-30 knots.

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