Former Tropical Storm Yinxing strengthened to a typhoon over the Western North Pacific Ocean east of the Philippines.  At 10:00 a.m. EST on Monday the center of Typhoon Yinxing was located at latitude 14.8°N and longitude 129.5°W which put the center about 610 miles (980 km) east of Manila, Philippines.  Yinxing was moving toward the northwest at 21 m.p.h. (33 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 987 mb.

Former Tropical Storm Yinxing strengthened to a typhoon east of the Philippines on Monday.  The inner end of a rainband wrapped around the center of Yinxing’s circulation.  An eye appeared to be forming at the center of Typhoon Yinxing.  Bands of showers and thunderstorms were revolving around the center of circulation.  Storms near the center of Yinxing generated upper level divergence that pumped mass away from the typhoon.

Winds to typhoon force extended out 35 miles in the eastern side of Typhoon Yinxing.  Winds to tropical storm force extended out 165 miles (265 km) from the center of Yinxing’s circulation.

Typhoon Yinxing will move through an environment favorable for intensification during the next 24 hours.  Yinxing will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southwestern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce southeasterly winds that will blow toward the top of Yinxing’s circulation.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Typhoon Yinxing will intensify during the next 24 hours.

Typhoon Yinxing will move around the southwestern part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Yinxing toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Yinxing will move toward the northern Philippines.  Yinxing could approach northern Luzon in three days.
