@gmanews: The four storms that churned simultaneously in the Western Pacific Ocean in November, battering most parts of the Philippines, is an “unusual” occurrence, the US-based National Aeronautics and Space Administration (NASA) said. “The Japan Meteorological Agency reported that it was the first time since records began in 1951 that so many storms co-existed in the Pacific basin in November,” said NASA. NASA shared a satellite image taken last November 11 where storms Yinxing (Marce), Toraji (Nika), Usagi (Ofel), and Man-Yi (#PepitoPH) were either approaching the Philippines or had already passed over the islands at that time.
