16TH SEPTEMBER 2017 MONSOON UPDATES AND WEEKLY WEATHER REPORT
Note on Monsoon watch
Pacific typhoon DOKSURI crossed Vietnam. This system will send a pulse to Bay of Bengal and a low pressure area likely to form in Bay of Bengal around 22nd of September. This will again revive the monsoon in the country. As per the GFS model the system will move North Westerly and reach up to Punjab. IMD will have to face in deciding for withdrawal of monsoon. Normal date has already passed. At this time withdrawal starts from West Rajasthan.
Realised Weather over Maharashtra, Goa and Gujarat State and Synoptic situation. (10th Septemberto 16thSeptember)
During the last week axis of monsoon trough was close to foothills of Himalayas on 10th September. From 11th to 16th though it shifted little south ward that is up to Jammu or Amritsar but position was north of normal position.
Low Pressure Systems:
Another important system was a cyclonic circulation over Kerala and trough from this system to Madhya Maharashtra across interior Karnataka. This system gave good rainfall over Maharashtra and Interior Karnataka. Two North – South trough were seen. One from Sub Himalayan West Bengal to East Jharkhand and another from East Bihar to North Odisha and third from Marathwada to South Kerala. But these troughs were not persisted for more than three days.
