Low pressure may bring rain to city by Friday

Chennai:11.12.2018
After evading Chennai for most part of this monsoon, rain clouds appear to be headed this way.
A low pressure intensifying in the Bay of Bengal is expected to bring a moderate spell of rain to the city and its neighbouring districts by this weekend, say weathermen. The weather system is likely to intensify into a depression in the next three days, leaving moderate to heavy rain in the coastal districts of south Andhra Pradesh and north Tamil Nadu.
While independent weather bloggers said there were chances of the system turning into a cyclone, IMD officials said it was too early to predict its intensity when it hits the coast.
IMD’s regional weather inference said the low pressure area over equatorial Indian Ocean and adjoining central parts of south Bay of Bengal with associated cyclonic circulation persists. The system is likely to become more marked during the next 48 hours. It is likely to concentrate into a depression in the subsequent 24 hours. “It is likely to move northwestwards towards north Tamil Nadu and south Andhra Pradesh coast,” an IMD official said.
“We are continuously monitoring the system. There may not be rain for the next three days. Whether the system will intensify after it becomes a depression, we will have to wait and watch,” said IMD deputy director general S Balachandran.
Independent weather bloggers said the system may intensify into a cyclone by this weekend. “The system most likely will become a cyclone by December 14. While it is too early to identify the location of its landfall, we will get more clarity in a couple of days,” said weather blogger Pradeep John.
Skymet Weather’s forecast shows that chances of the system intensifying into a cyclone are low. “At the most, it will become a deep depression. There’s very little time for it to become a cyclone. Whether it intensifies into a cyclone or not, coastal districts in north Tamil Nadu, including Chennai, will get moderate to heavy rain starting Friday,” said Skymet Weather chief meteorologist Mahesh Palawat.
Till last week, weather models indicated that the system would dissipate after turning into a well-marked low pressure. Experts said the models are now showing the system to be gathering more steam with favourable conditions in the sea and the atmosphere. Parameters like low vertical wind shear, low atmospheric pressure and high sea surface temperature are adding strength to the system that is now lying over south Bay of Bengal. “In December, weather systems usually form in south Bay of Bengal region due to high sea surface temperature,” said Palawat.
For the next 48 hours, IMD has forecast the Chennai skies to be generally cloudy. The maximum temperature will be 31 degrees Celsius and the minimum 24 degrees Celsius. Dry weather would prevail over the rest of Tamil Nadu.
