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 7.1n 112.2e,
approximately 210 nm northwest of brunei. Recent animated infrared
satellite imagery and a 011427z AMSU-b pass indicate a weak cyclonic
circulation with convective banding mostly on the northern flank.
Upper level analysis shows the area is south of the subtropical
ridge axis which is enhancing poleward outflow albeit with moderate
to high vertical wind shear. Maximum sustained surface winds are
estimated at 10-15 knots validated by a 011427z ascat pass. Minimum
sea level pressure is estimated to be near 1008 mb based on a ship
report at 011800z just to the north of the center. The potential for
the development of a significant tropical cyclone within the next
24 hours is 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.
3. Justification for reissue: added poor area in para 1.B.(1).
