TROPICAL DISTURBANCE WARNING 93W/95W

POSITION: 7.2N, 137.2E

WINDSPEED: 15KTS/28KPH

SLP:1010MB

MOVEMENT: STATIONARY.

POTENTIAL FOR 24HRS: GOOD.

TROPICAL DISTURBANCE WARNING 94W

POSITION: 15.6N, 123.6E

SLP: 1010MB

MOVEMENT: STATIONARY.

POTENTIAL FOR 24HRS: FAIR.

TROPICAL DISTURBANCE WARNING UNNAMED.

POSITION: 13.0N, 116.0E

WINDSPEED: 15KTS/28KPH

SLP: 1010MB

MOVEMENT: WEST SLOWLY

POTENTIAL: WEAK

RAINRATE:13-14mm/hr

SYNOPSIS: SOUTHWESTERLY WINDFLOW AND 94W OVER LUZON AND WESTERN VISAYAS, WEAK MONSOON TROUGH (ITCZ) OVER VISAYAS AND MINDANAO.

Tropical disturbance 93W renamed to 95W consolidated this time good as both its wind circulation, upper divergence, vortices and convections improved a lot for the past 12hrs indicating its potentials within 24hrs very possible. Upper levl divergence inceased to 30kts indicating its pressure dropping this time. 93/95W currently under the steering influence of competing building High over China and frontal system over NE. Poleward outflow improved fairly this time. 93/95W expected to become a Severe alert within 12 hrs and probably become a Minimal depression within 24-36hrs.

Elsewhere, unexpected development of 94W brought rain most of the day today mostly over Luzon. 94W developed due to interaction of 2 different strong wind system, from NE due to High pressure ridge and SW windflow that produces some mesocyclone circulation over the area. 94W is expected to remain as warninng as shear remain moderate over the area but poleward outflow warm SST and good OHC will maintain its intensity and potential is fair despite of low vortices over the area.

Elsewhere, another developing over South China sea. TRopical disturbance unnamed continues to developed as convection slowly building but not yet consolidating. potential for unnamed is weak within 24hrs but possible improvement likely within those hours.

Rain and thunderstorm still expected most of Luzon and western Visayas as SW windflow and monsoon trough continues to affect the area. Winds still strong at 63kph over Northern Luzon becoming moderate at 28kph over the rest of the country.
