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 13.0n
117.9e, is now located near 14.6n 111.4e, approximately 250 nm east-
southeast of hue, Vietnam. Animated multispectral satellite imagery
shows a weak low-level circulation center (LLCC) with poorly-
organized, flaring deep convection. A 042312z SSMI image shows
linear convective bands on the northern and southern periphery with
no indications of a well-defined LLCC. A ship observation from the
maharashtra, located near 14.5n 112.6e, indicated slp near 1007 mb
and light northeast winds. Additional ship observations west of the
LLCC showed slp values of 1009 mb and 15-20 knot convergent
westerlies. The LLCC is located within an overall marginal
environment under an upper-level, inverted trough and moving into
increasingly stronger vertical wind shear over the western South
China Sea. Maximum sustained surface winds are estimated at 10 to 15
knots. Minimum sea level pressure is estimated to be near 1007 mb.
The potential for the development of a significant tropical cyclone
within the next 24 hours remains poor.
(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.
