1. Western North Pacific area (180 to Malay Peninsula):
a. Tropical cyclone summary:
(1) at 230000z, typhoon 10w (matmo) was located near 24.4n
120.0e, approximately 92 nm west-southwest of Taipei, Taiwan, and
had tracked northwestward at 14 knots over the past six hours.
Maximum sustained surface winds were estimated at 70 knots gusting
to 85 knots. See ref a (wtpn31 pgtw 230300) for further details.
(2) no other tropical cyclones.
B. Tropical disturbance summary:
(1) the area of convection previously located near 12.8n
137.7e, is now located near 13.5n 136.0e, approximately 275 nm north-
northwest of Yap. Animated multispectral satellite imagery depicts a
highly elongated and poorly organized low level circulation center
with limited flaring convection along the northwest periphery. Upper
level analysis reveals an unfavorable environment as strong
northeasterly vertical wind shear (20 to 30 knots) continues to
hamper development. Model guidance continues to back off on the
timing of the development for this system until past tau 48. Maximum
sustained surface winds are estimated at 15 to 20 knots. Minimum sea
level pressure is estimated to be near 1008 mb. Due to the continued
unfavorable upper-level environment, the potential for the
development of a significant tropical cyclone within the next 24
hours is downgraded to 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.//
