PDC Disaster Alert, displaying PDC Active Hazards and Rainfall Accumulation (3-hour) layers.

However, there’s a tropical disturbance being referred to as Invest 99S…which is located approximately 150 NM northwest of Rowley Shoals, Australia

Here’s a NOAA satellite image, along with what the computer models are showing.

Here’s a near real-time wind profile of Invest 99S

According to the Joint Typhoon Warning Center (JTWC), satellite images show persistent deep convective cloud banding beginning to wrap into a developing low level circulation center.

Upper-level analysis shows a favorable environment, with low wind shear…and a well defined poleward outflow channel.

Global models show the system tracking southward towards the northwestern coast of Australia…while gradually strengthening before landfall.

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 has been upgraded to medium.

>>> Finally, there’s a second tropical disturbance being referred to as Invest 90S…which is located approximately 50 NM northeast of Cocos Island, Australia

Here’s a NOAA satellite image, along with what the computer models are showing.

Here’s a near real-time wind profile of Invest 90S

According to the Joint Typhoon Warning Center (JTWC), satellite images show formative cloud banding around the southern periphery of the low level circulation center.

Upper-level analysis shows a moderately favorable environment, with low 10-20 knot wind shear…and fair diffluence aloft.

Global models are developing the system within the next 24-36 hours, as it slowly tracks southeastward.

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 medium.

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.
