Typhoon Maysak continued to intensify on Sunday.  At 11:00 p.m. EDT on Sunday the center of Typhoon Maysak was located at latitude 8.4°N and longitude 146.9°E which put it about 370 miles south-southeast of Guam and about 600 miles east of Yap.  Maysak was moving toward the west at 17 m.p.h.  The maximum sustained wind speed was 100 m.p.h. and there were gusts to 125 m.p.h.  The minimum surface pressure was 959 mb.

Maysak is moving over warm Sea Surface Temperatures and it has plenty of energy available to support further intensification.  Upper level winds blowing from the southeast are creating some wind shear, but it is not enough to stop the intensification.  The circulation is symmetrical and it has well developed upper level outflow.  Maysak is expected to intensify for another day or two and it could become the equivalent of a major hurricane.

A subtropical ridge is steering Maysak on a track that is moving it just north of due west.  This motion is expected to continue for another 24 to 48 hours.  After that time the ridge is expected to weaken slightly and Maysak is expected to move more toward the northwest.  The center of Maysak should pass south of Guam during the next 12 hours.  On the projected track Maysak would approach Yap in about 36 hours.  It could be a very strong typhoon by that time and it would pose a distinct risk for Yap.
