Tropical Cyclone 14P (Yalo) is dissipating in the south Pacific…staying away from land

Here’s a satellite image of this tropical cyclone…and a near real time wind profile (spinning clockwise in the southern hemisphere)

Tropical cyclone 14P is located about 359 NM south of Papeete, Tahiti

According to the Joint Typhoon Warning Center (JTWC), satellite imagery depicts the presence of increasing wind shear over the past six hours…as the majority of convection is now decoupled from the system, revealing a fully exposed low level circulation center.

TC Yalo is experiencing significant 35-40 knot wind shear, while sea surface temperatures are cool…contributing to the rapid weakening.


Due to the deteriorating environment, Yalo will no longer be at tropical storm strength by the 12 hour forecast point, and the JTWC has issued its Final Warning

Maximum sustained winds as of the JTWC Warning #04 were 35 knots with gusts of 45 knots

Meanwhile, an area of disturbed weather is active in the Coral Sea circled in yellow above…that has a low chance of developing

This tropical disturbance was located about 425 NM east of Brisbane, Australia, here’s a satellite image…and a near real time wind profile

According to the Joint Typhoon Warning Center (JTWC), satellite imagery shows a fully exposed and well defined low level circulation center, with shallow convection. Microwave images and precipitable water vapor loops show significant dry air wrapping into the center.

Environmental analysis indicates that the system is located beneath an upper level low, producing subsidence aloft…and high wind shear.

Maximum sustained surface winds are estimated at 30-35 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. Therefore, the last regularly scheduled tropical weather outlook of the 2015 hurricane season has occurred. Routine issuance of the tropical weather outlook will resume on May 15, 2016. 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, 2016. Here’s the 2015 hurricane season summary

Central North Pacific

The central north Pacific hurricane season officially ended on November 30. Therefore, the last regularly scheduled tropical weather outlook of the 2015 hurricane season has occurred. Routine issuance of the tropical weather outlook will resume on June 1, 2016. During the off-season, special tropical weather outlooks will be issued as conditions warrant. Here’s the 2015 hurricane season summary
