JTWC upgraded this for TS Four. This system is gaining more sustained convection which it needs to fire up in the future. TS Warnings are in effect in Guam and this could be one to seriously watch and monitor.

WDPN31 PGTW 272100
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 04W (MAYSAK) WARNING NR
04//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 04W (MAYSAK), LOCATED APPROXIMATELY 747 NM
EAST-SOUTHEAST OF ANDERSEN AFB, GUAM HAS TRACKED WEST-NORTHWESTWARD
AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
(EIR) SATELLITE IMAGERY DEPICTS DEEP CURVED CONVECTIVE BANDING ALONG
THE NORTHERN AND EASTERN QUADRANTS WRAPPING INTO A TIGHTLY
CONSOLIDATED LOW LEVEL CIRCULATION CENTER (LLCC). THIS IS FURTHER
IDENTIFIED IN A 271757Z SSMIS MICROWAVE IMAGE THAT SHOWS THE BULK OF
CONVECTION IN THE BANDING ALONG THE NORTHERN PERIPHERY WITH DEEP
CENTRAL CONVECTION OVER THE LLCC. THE INITIAL POSITION IS BASED ON
THE AFOREMENTIONED MICROWAVE IMAGE AND EIR LOOP WITH GOOD
CONFIDENCE. THE CURRENT INTENSITY OF 35 KNOTS IS BASED ON CONSENSUS
DVORAK INTENSITY ESTIMATES FROM ALL AGENCIES AND SUPPORTED BY RECENT
SCATTEROMETRY DATA. TS 04W IS CURRENTLY LOCATED IN A FAVORABLE UPPER
LEVEL ENVIRONMENT WITH 10 TO 20 KNOT EASTERLY VERTICAL WIND SHEAR
(VWS) OFFSET BY STRONG DIVERGENCE ALOFT, WHICH IS EVIDENT IN THE
WATER VAPOR LOOP. TS MAYSAK IS TRACKING ALONG THE SOUTHERN PERIPHERY
OF THE DEEP LAYERED SUB-TROPICAL RIDGE (STR) TO THE NORTH.
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS 04W WILL CONTINUE TO TRACK WESTWARD UNDER THE INFLUENCE OF
THE DOMINANT STEERING STR THROUGH TAU 72. LOW VWS, EXCELLENT
OUTFLOW, AND HIGH SEA SURFACE TEMPERATURES (SSTS) ARE EXPECTED TO
PERSIST, RESULTING IN STEADY INTENSIFICATION.
C. AFTER TAU 72, TS MAYSAK WILL TRANSITION TO A WEST-
NORTHWESTWARD MOTION AS THE STEERING STR WEAKENS DUE TO A PASSING
SHORTWAVE TROUGH TO THE NORTH. TS 04W WILL CONTINUE TO INTENSIFY,
ALBEIT AT A SLOWER RATE, PRIOR TO LEVELING OUT AT 100 KNOTS. THIS
REDUCED INTENSIFICATION IS CAUSED BY AN INFLUX OF DRY STABLE AIR IN
THE PHILIPPINE SEA AND REDUCED OUTFLOW DUE TO THE WEAKENING STR;
HOWEVER, SSTS AND VWS WILL REMAIN FAVORABLE. DYNAMIC MODEL GUIDANCE
REMAINS IN TIGHT AGREEMENT, LENDING TO HIGH CONFIDENCE IN THE JTWC
TRACK FORECAST.

Actually no because there have been many storms in the past, but not as strong and powerful than this. We only had a weak tropical storm named Peipah last year, locally Domeng, hit Mindanao.
