The super typhoon Goni battered the Philippines on Sunday, 01 November with winds in excess of 250 kmph. The eyewall clouds and the inner rainbands dumped copious rains flooding the central region. The catastrophic winds and torrential rains damaged structures, uprooting trees, disrupting power lines and killing about 10 people. The international airport was closed and about 10 Lakh people were evacuated along the projected path of the cyclone. This was the 18th cyclone of the season to hit the country and the strongest this year so far. The typhoon season lasts till 30th November for the Northwest Pacific Ocean and the South China Sea.
The typhoon has now crossed over to the South China Sea and weakened to a tropical storm Rolly. It is going to retain strength, move westward over the ocean for the next 72 hours and strike Vietnam on 5th November. The system will weaken thereafter and move over to Cambodia and spare Laos. In its last leg, the weather system will move across Thailand and Myanmar as a well marked low pressure area. The remnant of the system is likely to emerge over Northeast Bay of Bengal by fag end of this week. This could be the next low pressure area after the persisting one over the Northeast and the Central Bay of Bengal.
The remnants of West Pacific weather systems in the Bay of Bengal have a significant role in conducting Northeast Monsoon activity. These leftovers also stand chance to intensify into Post Monsoon cyclone subject to long sea travel. The Sea Surface Temperature and prevailing winds generally remain conducive for cyclogenesis.
