Tropical depression finds its way to Central Visayas

Tuesday, April 15, 2008

Tropical depression Ambo found its way to Central Visayas in the middle of summer at a speed of 45 kilometers per hour.

Philippine Atmospheric Geophysical Astronomical Services Administration-Visayas head Oscar Tabada said Storm Signal Number 1 was raised over Dumaguete City to northern part of Oriental Negros and southern part of Cebu yesterday dawn.

As of 2 p.m. yesterday, Ambo was leaving Dumaguete City towards Palawan, Tabada said. It is expected to be at the vicinity of Puerto Princesa City this morning.

Tabada said it is not unusual for a typhoon to hit the country during summer. He said tropical disturbances are expected to enter the country any month, although most of them occurred during the southwest monsoon season.

Tropical depressions during southwest monsoon season, which occurs from July to August, are mostly happening in Luzon.

During the northeast monsoon, Tabada said, the Visayas and Mindanao are usually affected by weather disturbances.

Since 1940, there were two tropical disturbances recorded to have occurred in the month of April. The first one was in 1991 with tropical depression “Bebeng.”

In 1994, topical storm “Besing” occurred also in April and caused several damages to lives, crops and properties.

Office of Civil Defense spokesperson Neil Sanchez said there were no reports on damages or casualties brought about by Ambo from the local government units. — Ferliza C. Contratista with Anthony S. Teo/LPM

Why did you change the name? It is Tropical Storm 02W. If you want, put Tropical Depression (JMA)/Tropical Storm 02W (JTWC).

Unless something has changed, we use official names for systems. Officially, this system is a TD.

Then drop the 02W because the JMA does not number TDs. Its official name is tropical depression.

China Meteorological Agency (CMA) bulletin, something like JTWC's TCFA.:

目前在南海南部海面有热带低压活动,今天上午8点钟低压中心位于我国海南省三亚市东南方向大约1250公里的南海南部海面上,就是北纬10.0度,东经117.4度,中心附近最大风力有7级(15米/秒)。

预计,低压中心将以每小时15公里左右的速度向西偏北方向移动,以后将转向西北方向移动,强度逐渐加强,并有可能于未来24小时内发展成为今年第1号热带风暴。受其影响,未来两天,南海南部和中部海面将有6-8级大风,部分海域阵风可达9-10级。


A tropical depression is currently active in the south of South China Sea, at 0800 Beijing Time (GMT+8) it is centered at 1250km southeast of Sanya City, Hainan, i.e. 10N 117.4E. The maximum sustained winds near the center is 7 bft (15m/s)

The center of the depression will move West northwestward at 15km/h and should intensify. Thus is probable that it become the No.1 Tropical Storm of this year during next 24 hours. Under its influence, during the next 24-48 hours, 6-8 bft wind gusting to 9-10 bft will occur in the south and central part of the South China Sea.
