However, there’s a tropical disturbance, which is being referred to as Invest 93W…located approximately 330 NM southwest of Guam

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

Upper level analysis reveals a generally favorable environment, with good outflow, both poleward and equatorward…and low wind shear values.

Global models suggest the system will recurve, with a small window for development…before encountering the entrenched westerly jet stream at near 20 degrees north latitude. The current thought is that this system won’t directly impact Okinawa.

Maximum sustained winds are estimated to be 20-25 knots.

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

Finally, there’s a second tropical disturbance, which is being referred to as Invest 97P…located approximately 270 NM northeast of Darwin, Australia

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

According to the Joint Typhoon Warning Center (JTWC), satellite images show fragmented convective cloud banding, wrapping into an elongated low level circulation center.

The system is currently located in an area of good overall outflow, low wind shear (5-10 knots), and warm sea surface temperatures.

Global models suggest a slow intensification, as the system moves southwestward over the next several 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

The eastern Pacific hurricane season officially ended on November 30, 2016. Therefore, the last regularly scheduled tropical weather outlook of the 2016 hurricane season has occurred. During the off-season, special tropical weather outlooks will be issued as conditions warrant. The Pacific Disaster Center (PDC) will begin coverage of the eastern Pacific again on May 15, 2017.
