It's been raining here non-stop since morning albeit just moderately(but now it's starting to get heavy as I type this). There's some occasional gust but not that strong.


I'm in Tagaytay city (elev - approx 2000 ft. asl)- near the Cavite-Batangas Border
Where are they in Cavite? some low lying areas like Rosario, Noveleta, Cavite City, Bacoor and Kawit are quite flood prone.

Down to 45 knots and south of Manila...

SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 22W (HAGUPIT) WARNING
NR 31//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 22W (HAGUPIT), LOCATED APPROXIMATELY 51 NM
SOUTH-SOUTHEAST OF MANILA, PHILIPPINES, HAS TRACKED WEST-
NORTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED (EIR) SATELLITE IMAGERY DEPICTS INCREASED DEEP CENTRAL
CONVECTION OBSCURING THE LOW-LEVEL CIRCULATION CENTER (LLCC). AN
081057Z SSMIS MICROWAVE IMAGE REVEALS TIGHTLY-CURVE BANDING OVER THE
NORTHERN SEMI-CIRCLE WRAPPING INTO THE LLCC. THE CURRENT POSITION IS
BASED ON THE EIR ANIMATION, THE AFOREMENTIONED MICROWAVE IMAGERY AND
SATELLITE FIXES FROM PGTW AND RJTD WITH GOOD CONFIDENCE. DVORAK
INTENSITY ESTIMATES OVER THE PAST 24 HOURS MAY NOT BE REPRESENTATIVE
DUE TO LAND INFLUENCES; THEREFORE, THE INITIAL INTENSITY OF 45 KNOTS
IS BASED ON THE WEAKENING TREND AND OVERALL CURRENT STRUCTURE. UPPER-
LEVEL ANALYSIS INDICATES TS 22W IS LOCATED IN AN AREA OF MODERATE
(20 KNOT) VERTICAL WIND SHEAR OFFSET BY A ROBUST POLEWARD OUTFLOW
CHANNEL TAPPING INTO THE MID-LATITUDE WESTERLIES. TS 22W IS
CURRENTLY TRACKING ALONG THE SOUTHWESTERN PERIPHERY OF A SUBTROPICAL
RIDGE (STR) TO THE NORTHEAST.
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS HAGUPIT WILL CONTINUE TO TRACK WEST-NORTHWESTWARD OVER THE
NEXT 24 HOURS UNDER THE STEERING INFLUENCE OF THE STR TO THE
NORTHEAST. BY TAU 36, TS 22W IS FORECAST TO EMERGE INTO THE SOUTH
CHINA SEA (SCS) AND IS EXPECTED TO SHIFT WEST-SOUTHWESTWARD AS
RIDGING BUILDS IN NORTH OF THE SYSTEM ACROSS THE SCS. TS 22W WILL
CONTINUE ITS WEAKENING TREND ACROSS THE SCS AS IT INTERACTS WITH THE
COOLER, MORE STABLE AIR ASSOCIATED WITH THE NORTHEASTERLY SURGE
EVENT.
C. AFTER TAU 72, TS HAGUPIT IS EXPECTED TO WEAKEN RAPIDLY AS IT
INTERACTS WITH THE SOUTHERN COAST OF VIETNAM, LEADING TO DISSIPATION
BY THE END OF THE FORECAST PERIOD. MODEL GUIDANCE REMAINS IN TIGHT
AGREEMENT, LENDING HIGH CONFIDENCE IN THE JTWC TRACK FORECAST WHICH
IS POSITIONED CLOSE TO THE MULTI-MODEL CONSENSUS.//

Bet you are watching ABS-CBN (TFC) as they use that symbol even if its a tropical depression... The presenter isnt even a forecaster! Not unlike in the other station (GMA) where their weather presenter is a former head of PAGASA Weather branch.

It's still raining and the winds are still strong for more than 24 hours here in Batangas. The storm is not going anywhere!
