JTWC ARE ISSUING 6HOURLY WARNINGS AND 3HOURLY SATELLITE BULLETINS ON 16W.
TD 16W. WARNING 15 ISSUED AT 14/03UTC. THERE ARE NO SIGNIFICANT CHANGES TO THE FORECAST FROM THE PREVIOUS WARNING. FORECAST DISCUSSION: TD 16W IS EXPECTED TO TRACK WESTWARD ALONG THE SOUTHERN PERIPHERY OF THE SUBTROPICAL RIDGE(STR) THROUGH 72H THEN TURN WEST-NORTHWESTWARD THROUGH 120H AS IT TRACKS ALONG THE SOUTHWEST PERIPHERY OF THE STR. TD 16W SHOULD EVENTUALLY BEGIN STRENGTHENING AFTER 36 TO 48 HOURS AS INDICATED IN THE BULK OF THE INTENSITY GUIDANCE WITH A MORE RAPID INTENSIFICATION TREND AFTER 72H2 WITH A PEAK INTENSITY OF 70 KNOTS/CAT 1 ANTICIPATED BY 120H.

TD 16W. SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION: ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS DEEP CONVECTION FLARING OVER A BROAD, PARTIALLY-EXPOSED, RAGGED LOW-LEVEL CIRCULATION (LLC), WHICH SUPPORTS THE INITIAL POSITION WITH MEDIUM CONFIDENCE. ALTHOUGH VERTICAL WIND SHEAR VALUES ARE LOW, DIFFLUENT UPPER-LEVEL EASTERLY FLOW OF 20-25 KNOTS OFFSET BY MODERATE POLEWARD OUTFLOW, ENHANCED BY A TUTT CELL TO THE NORTHWEST, AND DRY AIR ENTRAINMENT ARE HINDERING SUSTAINED CONVECTION AND LIMITING DEVELOPMENT. THE INITIAL INTENSITY OF 30 KNOTS IS ASSESSED WITH MEDIUM CONFIDENCE BASED ON THE PGTW DVORAK ESTIMATE.
TD 16W.MODEL DISCUSSION: THERE IS SIGNIFICANT UNCERTAINTY (MEDIUM OVERALL) IN THE EXACT TRACK WITH A SPREAD OF 305KM AT 72H NEAR GUAM. DUE TO THE BROAD NATURE OF THE LOW LEVEL CIRCULATION(LLC), THERE IS ADDITIONAL UNCERTAINTY IN THE INITIAL POSITION OF THIS BROAD LLC, WHICH COULD LEAD TO MINOR SHIFTS IN THE TRACK AS THE SYSTEM STRUGGLES TO CONSOLIDATE OVER THE NEXT TWO DAYS. INTENSITY GUIDANCE IS IN GOOD AGREEMENT THROUGH 48H BUT DIVERGES AFTER 48H WITH HWRF INDICATING A PEAK INTENSITY OF 110 KNOTS/CAT 3 AT 120H AND THE JTWC INDICATING A PEAK INTENSITY OF 70 KNOTS/CAT 1 AT 120H. DUE TO THE MARGINALLY FAVORABLE CONDITIONS AND BROAD NATURE OF THE SYSTEM, THIS FORECAST IS SOMEWHAT CONSERVATIVE. OVERALL, THERE IS LOW CONFIDENCE IN THE INTENSITY FORECAST.
EASTERN PACIFIC. HU 12E(LINDA). WARNING 16 ISSUED AT 14/04UTC. CURRENT INTENSITY IS 105KNOTS/CAT 3 AND IS FORECAST TO PEAK AT 110KNOTS/CAT 3 AT 14/12UTC.
