MANILA (2nd UPDATE) - Another possible tropical cyclone is forming in the skies off eastern Philippines, less than a day after Typhoon Glenda hammered Luzon island.

The US Joint Typhoon Watch Center (JTWC) on Wednesday raised the status of a new weather disturbance in the South Pacific.

The Hawaii-based US Navy and US Air Force agency said it now has a high potential in developing into a significant tropical cyclone within the next 24 hours.

The weather disturbance was last spotted near Palau.

"Animated enhanced infrared satellite imagery depicts a rapidly consolidating low level circulation center with formative convective banding along the southern periphery and persistent central convection," JTWC said in its tropical cyclone formation alert.

"Convection has continued to improve. Upper level analysis reveals a favorable environment with good equatorward outflow and low vertical wind shear," it added. "Sea surface temperatures in the area are conducive for development."

"Maximum sustained surface winds are estimated at 15 to 20 knots. Minimum sea level pressure is estimated to be near 1005 mb," the cyclone formation alert said. "The potential for the development of a significant tropical cyclone within the next 24 hours is high."

State weather bureau PAGASA said Wednesday it is also monitoring the low pressure area located around 1,090 kilometers east of the Visayas.

If the low pressure area doesn't dissipate, it may enter the Philippine area of responsibility (PAR) either on Friday or Saturday, PAGASA said.

It will be named "Henry" if the weather disturbance further develops into a tropical cyclone and enters PAR.

The Japan Meteorological Agency, meanwhile, has already upgraded the weather disturbance into a tropical depression. - with a report from Bettina Magsaysay, ABS-CBN News
