1. Western North Pacific area (180 to Malay Peninsula):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary:
      (1) the area of convection (invest 99w) previously located 
near 10.7n 144.2e, is now located near 11.4n 144.2e, approximately 
120 nm south-southwest of andersen AFB, Guam. Animated 
multispectral satellite imagery and a 200504z AMSU 89ghz partial 
image depict an elongated and disorganized weak low level 
circulation center (LLCC) with scattered convection in the northern 
and eastern peripheries. The upper level analysis reveals a 
moderately favorable environment for development with weak vertical 
wind shear (10-15 knots).  Global models are in agreement 
that the system will remain weak and dissipate as it travels 
westward over the next 24 hours. Maximum sustained surface winds 
are estimated at 10 to 15 knots. Minimum sea level pressure is 
estimated to be near 1009 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.//
