1. Western north pacific area (180 to malay peninsula):
   a. Tropical cyclone summary: none.
   b. Tropical disturbance summary:
      (1) the area of convection previously located near
12.6n 140.9e, is now located near 12.6n 139.9e,
approximately 225 nm north-northeast of yap. Animated
multispectral satellite imagery shows a broad, but
quickly consolidating, low level circulation center with
improved convective banding. A 300031z partial ascat
pass revealed an improved low level structure while a
300711z ssmis 37ghz microwave image showed the banding
features are becoming more defined. Upper level analysis
reveals a favorable environment, with low to moderate
(10 to 15 knots) vertical wind shear and good outflow.
Sea surface temperatures in the region are conducive for
development. Maximum sustained surface winds are
estimated at 15 to 20 knots. Minimum sea level pressure
is estimated to be near 1004 mb. Model guidance has
become more aggressive with development in the next 24
to 48 hours as this system proceeds west. Due to the
continually improving structure of the system and model
development, the potential for the development of a
significant tropical cyclone within the next 24 hours is
upgraded to high. See ref a (wtpn21 pgtw 300900) for
further details.
      (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: upgraded area in para
1.b.(1) to 
high.//
