EFFECTS & HAZARDS SUMMARY TROPICAL CYCLONE WATCH CURRENT SW MONSOON INTENSITY: WEAK >> Partly sunny to cloudy with possible occasional rains, squalls, showers or thunderstorms will be expected along the following affected areas: WESTERN SECTIONS OF NORTHERN AND CENTRAL LUZON Light to moderate SW'ly winds (not in excess of 40 kph) will blow.
MA-ON's (08W) circulation has improved further, with a more radial look but symmetrical. Below are the summary of the storm's parts and its hazards affecting specific areas: INNER RAINBANDS (with a developing CDO) - over water...not affecting any land areas. Tropical Storm Conditions w/ Tropical Storm Force Winds (62-95 kph) can be expected along these bands. OUTER RAINBANDS - over water...not affecting any land areas. Tropical Depression Conditions w/ moderate to strong winds (30-61 kph) can be expected along these bands (click here to know more about Rainbands). 24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 150 mm (low to high rainfall) can be expected along the rainbands...with isolated amounts of up to 400 mm (high) near the center of MA-ON (08W). (click to open NOAA's eTRaP graphic).

JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 2 AM (18 GMT) WED 13 JULY POSITION: 19.1N 153.6E.
*TROPICAL STORM (TS) 08W (MA-ON), LOCATED APPROXIMATELY 760 NM
EAST-SOUTHEAST OF IWO TO, JAPAN, HAS TRACKED WEST-NORTHWESTWARD AT
08 KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED INFRARED SATELLITE
IMAGERY SHOWS TWO FLARING CONVECTIVE LOBES STRADDLING THE WESTERN
AND EASTERN PERIPHERIES OF THE LOW LEVEL CIRCULATION CENTER (LLCC)
AS CONVECTIVE DIURNAL MAXIMUM NEARS. A 12/1551Z AMSR-E 89H
GHZ AND 12/1541Z AMSU 89 GHZ IMAGE SHOW THAT THE DEEP CONVECTION IS
CONCENTRATED IN A THIN LINEAR BAND TO THE WEST WITH A LARGER CURVING
BAND TO THE EAST OF THE LLCC. THE 12/1551Z 37H GHZ AMSR-E IMAGE
SHOWS THAT THE LLCC IS STILL ELONGATED IN A WEST TO EAST ORIENTATION
AND VERY ASYMMETRIC IN NATURE. RECENT UPPER AIR STREAMLINE ANALYSIS
AND ANIMATED WATER VAPOR IMAGERY SHOW THAT A POINT SOURCE OF
DIVERGENCE HAS DEVELOPED OVER TS 08W BUT MAXIMUM UPPER LEVEL
DIVERGENCE REMAINS CONCENTRATED ON THE EASTERN SEMICIRCLE OF THE
SYSTEM. THE WESTERN AND NORTHERN PORTIONS OF THE STORM ARE STILL
BEING NEGATIVELY AFFECTED BY THE UPPER LEVEL CONVERGENCE AND
SUBSIDENCE CAUSED BY THE TROPICAL UPPER LEVEL TROPOSPHERIC TROUGH
(TUTT) CELL TO THE NORTHWEST AND GENERAL UPPER LEVEL TROUGHING TO
THE NORTH. HOWEVER, THE TUTT CELL TO THE NORTHWEST HAS BEEN
PROPAGATING WESTWARD FASTER THAN THE MOTION OF TS 08W AND HAS
INCREASED ITS DISTANCE FROM THE STORM WHICH IS ALLOWING FOR A
NORTHWESTWARD POLEWARD OUTFLOW CHANNEL TO DEVELOP. THE OUTFLOW INTO
THE LARGE TUTT CELL, THAT LIES FAR TO THE EAST-NORTHEAST NEAR THE
DATELINE, IS BEGINNING TO WEAKEN AS TS 08W INCREASES ITS
LONGITUDINAL DISTANCE FROM THE CELL. MODEL GUIDANCE REMAINS TIGHTLY
CLUSTERED WITH THE EXCEPTION OF UKMET WHICH LIES TO THE SOUTH OF
CONSENSUS AND FAVORS A CONTINUED WESTWARD TRACK. THIS FORECAST
FAVORS A NORTHWARD RECURVATURE SCENARIO, AS THE MAJORITY OF
CONSENSUS MEMBERS DO, IN THE LATER TAUS...(more info)
