1. Western North Pacific area (180 to Malay Peninsula):
a. Tropical cyclone summary:
(1) at 220000z, tropical depression 26w (twentysix) was
located near 6.4n 148.8e, approximately 190 nm west-southwest of
Chuuk island, and had tracked northeastward at 03 kts over the past
six hours. Maximum sustained surface winds were estimated at 25
knots gusting to 35 knots. See ref a (wtpn31 pgtw 220300) for
further details.
(2) no other tropical cyclones.
B. Tropical disturbance summary:
(1) the area of convection previously located near 6.7n
129.0e, is now located near 7.8n 128.9e, approximately 340 nm west
of Palau. Animated multispectral satellite imagery continues to show
consolidation of deep convection near a well-defined low level
circulation center (LLCC). A 212327z trmm microwave image shows
multiple convective bands converging into the system center while
the increasingly symmetric LLCC is evident in a 220038z ascat pass.
However, the LLCC has been partially-exposed in visible imagery over
the last 6 to 12 hours as the deep convection has been sheared
slightly to the west. Additionaly, though the system has some
divergent flow aloft, it currently lacks a good outflow mechanism.
Maximum sustained surface winds are estimated at 17 to 22 knots.
Minimum sea level pressure is estimated to be near 1006 mb. The
potential for the development of a significant tropical cyclone
within the next 24 hours remains fair.
(2) no other suspect areas.
2. South Pacific area (west coast of South America to 135 east):
a. Tropical cyclone summary: none.
B. Tropical disturbance summary: none.//
