Tropical Cyclone Activity Report – Pacific / Indian Oceans

Tropical Cyclone 03W remains active…located about 256 NM northwest of Yap

PDC Disaster Alert, displaying PDC Active Hazards, Tropical Cyclone segments, positions, wind radii, for Tropical Cyclone 03W

Tropical Cyclone 03W will be modestly strengthening…although remaining over the open ocean away from land

Here’s the latest NOAA satellite image of this system – and what the computer models are showing.

Here’s a near real-time wind profile of TC 03W

According to the Joint Typhoon Warning Center (JTWC), satellite images show the system has maintained overall convective signature, as it slowly consolidates.

Environmental analysis indicates favorable conditions, with low wind shear, warm sea water temperatures…and excellent poleward outflow.

TC 03W will continue tracking northwestward over the next 24 hours. Thereafter, it will shift north and finally northeast.

Increased outflow and low wind shear values over the next 24-36 hours, will promote moderate intensification, peaking at near 45 knots. Then, increased wind shear associated with the prevailing westerlies rapidly erode…and then dissipate the storm within 72 hours.

Maximum sustained winds as of the JTWC Warning #2 were 30 knots with gusts of 40 knots.

Meanwhile, there’s a tropical disturbance, which is being referred to as Invest 97P…located approximately 275 NM north 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 an elongated low level circulation, with persisting convection beginning to wrap into the center.

The disturbance is currently located in a marginal although improving environment, with high wind shear of 25 knots. This however is being offset by strong poleward upper level outflow, and very warm sea surface temperatures.

Global models are in agreement that the disturbance will continue to track to the southwest over the next several days, although are in disagreement to when and how strongly the system will intensify.

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 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.

Central North Pacific

The central north 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 central Pacific again on June 1, 2017.
