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

   a. Tropical cyclone summary: none.

   B. Tropical disturbance summary:

      (1) the area of convection previously located near 4.4n

148.4e, is now located near 3.0n 155.1e, approximately 320 nm

southeast of Chuuk. Animated multispectral satellite imagery shows

curved banding around a developing low level circulation center

(LLCC). Upper level analysis indicates the system is located beneath

diffluence aloft and in an area of low vertical wind shear. An

observation in the vicinity is reporting high sea surface

temperatures (sst) of 29 degrees celsius, favorable for development.

Maximum sustained surface winds are estimated at 15 to 20 knots.

Minimum sea level pressure is estimated to be near 1008 mb. Due to

upper level diffluence and high SST, the potential for the

development of a significant tropical cyclone within the next 24

hours is upgraded to fair.

      (2) no other suspect areas.

2. South Pacific area (west coast of South America to 135 east):

   a. Tropical cyclone summary:

      (1) at 190000z, tropical cyclone 20p (ului) was located near

16.5s 156.7e, approximately 630 nm east of Cairns, Australia, and

had tracked southwestward at 06 knots over the past six hours.

Maximum sustained surface winds were estimated at 65 knots gusting

to 80 knots. See ref a (wtps31 pgtw 190300) for further details.

      (2) no other tropical cyclones.

   B. Tropical disturbance summary: none.//
