1. Western North Pacific area (180 to Malay Peninsula):

   a. Tropical cyclone summary:

      (1) at 240000z, tropical depression 27w (twentyseven) was

located near 9.7n 127.1e, approximately 55 nm east-northeast of

mindinao, and had tracked northwestward at 03 knots over the past

six hours. Maximum sustained surface winds were estimated at 30

knots gusting to 40 knots. See ref a (wtpn32 pgtw 240300) for

further details.

      (2) at 240000z, tropical storm 26w (Nida) was located near

8.6n 145.6e, approximately 290 nm south-southeast of Guam, and had

tracked westward at 08 knots over the past six hours. Maximum

sustained surface winds were estimated at 55 knots gusting to 70

knots. See ref b (wtpn31 pgtw 240300) for further details.

      (3) no other tropical cyclones.

   B. Tropical disturbance summary:

      (1) the area of convection previously located near 4.5n

107.2e, is now located near 6.2n 107.0e, approximately 355 nm north-

northeast of singapore. Animated multispectral satellite imagery

shows deep convection remains persistent near a quasi-stationary low

level circulation center (LLCC). Animated enhanced water vapor

imagery shows convection has consolidated to the western periphery

of the LLCC, with good poleward outflow persisting. A 240205z AMSU-b

image supports the current position and organizational structure of

the LLCC. Upper-level analysis indicates the system is located

equatorward of the subtropical ridge axis with radial outflow and

favorably low vertical wind shear. Maximum sustained surface winds

are estimated at 15 to 20 knots. Minimum sea level pressure is

estimated to be near 1005 mb. The potential for the development of a

significant tropical cyclone within the next 24 hours remains good.

See ref c (wtpn22 pgtw 231100) for further details.

      (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.//
