The latest storm and low pressure information from the Philippine weather agency PAGASA released at 4:00 a.m. on November 9 said that at 3:00 a.m. on the same day, low pressure 11b - formed near the Philippines from November 8 - was about 1,150 km east of southeast Luzon. At 2:00 a.m. the same day, the depression entered the Philippine PAR forecast area. It is forecasted that low pressure 11b is likely to strengthen into a tropical depression within the next 24 hours.
Meanwhile, a new low pressure - low pressure 11c - has formed near the Philippines right after 11b. At 2:00 a.m. on November 9, Depression 11c was about 2,885 km east of northeast Mindanao, outside the PAR. PAGASA forecasts that the new low pressure is likely to strengthen into a tropical depression in the next 24 hours.
The Philippine weather agency noted that two new low pressure areas have formed and are forecast to strengthen while Typhoon Yinxing (called Marce in the Philippines) has entered the East Sea.
At 3:00 a.m. on November 9, Typhoon Yinxing - currently the 7th storm in the East Sea - was about 500 km west of Laoag, Ilocos Norte, Philippines, with maximum sustained winds of 155 km/h near the center, gusts of 190 km/h and moving west-northwest at a speed of 20 km/h.
According to the Japan Meteorological Agency (JMA), the TDb - the low pressure system that the Philippines calls 11c - will definitely enter the East Sea.
The latest storm forecast from the JMA states that the TDb depression will strengthen into a tropical storm as early as November 9 and maintain the storm intensity until at least November 13 when the forecast period ends.
The storm is likely to make landfall in the Philippines on November 11 and enter the South China Sea - becoming the eighth storm in the South China Sea - after this period.
Meanwhile, the latest storm and low pressure information from the US Navy's Joint Typhoon Warning Center (JTWC) said that in addition to the two low pressure areas near the Philippines, which the JTWC calls Invest 92W, Invest 93W, the third low pressure area - Invest 94W - has also formed.
The latest depression is located in the western Pacific Ocean. It is forecasted that low pressure Invest 94W is likely to strengthen into a storm in the next 24 hours. The new low pressure has maximum sustained surface winds of about 25-35 km/h.
JTWC forecasters said that low pressure Invest 94W is in a favorable environment to strengthen further, with low to moderate wind shear (15-20 nautical miles), warm sea surface temperatures (30-31 degrees Celsius). Forecast models predict that low pressure Invest 94W will continue to move northwest with stable intensity over the next 2 days.
