1. Western North Pacific area (180 to Malay Peninsula):
a. Tropical cyclone summary:
(1) at 181800z, tropical storm 04w (leepi) was located near
19.8n 126.5e, approximately 408 nm southward of Kadena AB, and had
tracked northward at 08 knots over the past six hours. Maximum
sustained surface winds were estimated at 35 knots gusting to 45
knots. See ref a (wtpn31 pgtw 182100) for further details.
(2) no other tropical cyclones.
B. Tropical disturbance summary:
(1) an area of convection has persisted near 12.5n 115.4e,
approximately 600 nm south of Hong Kong. Animated infrared satellite
imagery depicts a weak low-level circulation center (LLCC) with
disorganized-flaring deep convection. A 182001z SSMI microwave image
indicates no discernible LLCC, however, there are hints of
fragmented banding over the southern semi-Circle of the LLCC. A
nearby ship report indicates 11 knot winds at 1002 mb. The system is
located within a favorable environment of low (5 to 10 kts) vertical
wind shear (vws) and warm (~30 deg celsius) sea surface temperatures
(ssts). Upper level analysis indicates good divergence aloft with
the potential for enhanced outflow by a TUTT cell located near 22n
120e. Dynamic models indicate that the system will develop into a
tropical depression within the next 2 to 3 days with a track
meandering northward within the South China Sea. Maximum sustained
surface winds are estimated at 10 to 15 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 is low.
(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.
