1. Western North Pacific area (180 to Malay Peninsula):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary:
      (1) an area of convection (invest 90w) has persisted near 6.9n
135.4e, approximately 50 nm southeast of Palau. Animated enhanced
infrared satellite imagery depicts a large amount of convection
located over a low level circulation center with feeder bands
wrapping in from the east.  The disturbance is currently located in
an area of good divergence aloft, low vertical wind shear (10-15
knots), and very warm sea surface temperatures (30-31 celsius).
Currently global models are split as to the track of this
disturbance and are currently not showing development. Maximum
sustained surface winds are estimated at 10 to 15 knots. Minimum sea
level pressure is estimated to be near 1010 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.
3. Justification for reissue: added area in para 1.B.(1) as a low.//
