1. Western North Pacific area (180 to Malay Peninsula):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary:
      (1) an area of convection has persisted near 9.4n 131.8e, 
approximately 705 nm east-southeast of Manila, Philippines. Animated 
multispectral satellite imagery depicts a broad, developing low-
level circulation center (LLCC) with disorganized deep convection 
flaring over the system. A 250046z metop-b 89 ghz image reveals a 
disorganized LLCC with weak banding. Upper-level analysis indicates 
that the system is located equatorward of the subtropical ridge axis 
and is under diffluent flow with moderate to strong (20 to 30 knots) 
vertical wind shear. 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 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.//
