1. Western North Pacific area (180 to Malay Peninsula):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary:
      (1) an area of convection (invest 97w) has persisted near 9.5n 
153.8e, approximately 570 nm east-southeast of Guam. Animated 
multispectral satellite imagery depicts weak and disorganized 
convection with mid level rotation. Recent scatterometry data 
suggests a tropical wave at the surface. Upper level analysis 
reveals a poor environment with moderate to strong (15-25 knots) 
vertical wind shear and weak outflow. Maximum sustained surface 
winds are estimated at 10 to 15 knots. Minimum sea level pressure is 
estimated to be near 1007 mb. Models show the system generally 
moving to the northwest over the next several days. Due to the poor 
organization at the surface 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.//
