Info

Betty was upgraded to a tropical stormat 1200Z on the Ith based upon receipt of35 kt ship reports and satellite imageryshowing improved convective organization.Aircraft reconnaissance at 080034z indicatedthat Tropical Storm Betty had intensifiedfurther with maximum surface winds of 50 kt(26 m/s) being reported in a small area inthe east semicircle.The Hong Kong Royal Observatory (WMO45005) picked up Betty on weather radar atapproximately 080300z and transmittedposition fixes until 090600Z. These hourlyreports aided greatly in positioning thetropical storm during this period.Between 0600z on the 8th and 0600Z onthe 9th, Betty maintained an intensity of50 to 55 kt (26 to 28 m/s), making landfallat 090300z approximately 135 nm (250 km)west-southwest of Hong Kong. Figure 3-04-3shows Betty at maximum intensity just priorto landfall. Dissipation occurred after091800z over the southwestern portion ofthe Peoples Republic of China. No forecastproblems were encountered with TropicalStorm Betty since it moved steadily to thenorthwest around the southwestern peripheryof the subtropical ridge.f~gwte 3-04-3. rJLQpid ~22Y0rI &.t@O.tmO,%imwnLmtm$itg oi 55 tat (2g mlbl jtif ptioz .tQ &wd@.U(090737Z Jutg v~p v~~ -GWWLY1 .29
