TYPHOON 19W (VONGFONG), LOCATED APPROXIMATELY 498 NM NORTH-
NORTHWEST OF YAP, HAS TRACKED WEST-NORTHWESTWARD AT 13 KNOTS OVER
THE PAST SIX HOURS. THE CURRENT POSITION ESTIMATE IS BASED, WITH
HIGH CONFIDENCE, ON A RECENT PGTW SATELLITE EYE FIX AND A 070518Z
SSMI IMAGE. THE CURRENT INTENSITY OF 120 KNOTS IS CONSISTENT WITH
DVORAK T-NUMBER ESTIMATES RANGING FROM 5.5 TO 6.5 AND WITH RECENT
AUTOMATED DVORAK INTENSITY ESTIMATES. TY 19W HAS CONTINUED TO
RAPIDLY INTENSIFY OVER THE PAST SIX HOURS, EVIDENCED BY SYMMETRIC
BANDING AND A 27 NM DIAMETER EYE EVIDENT IN RECENT SATELLITE
IMAGERY. UPPER-LEVEL ANALYSIS INDICATES LOW VERTICAL WIND SHEAR AND
MULTIPLE OUTFLOW MECHANISMS, INCLUDING A TROPICAL UPPER-TROPOSPHERIC
TROUGH (TUTT) CELL POSITIONED TO THE EAST. TY 19W CONTINUES TRACKING
GENERALLY WESTWARD ALONG THE SOUTHERN PERIPHERY OF A DEEP-LAYERED
SUBTROPICAL STEERING RIDGE.
