Chennai: Chennai rains are back again not because of yesterday’s thunderous showers in the city but due to the fact that the low pressure area over Bay of the Bengal is not likely to die down anytime soon.
As per the proverb slow and steady wins the race, the circulating winds are slowly and sure-footedly inching closer to our coast creating a situation for heavy rainfall.
Met department said the north coastal regions of Tamilnadu, including Chennai, are likely to witness heavy rains in the next 24 hours.
An official said, “Yesterday’s low pressure area over Bay of Bengal has moved further westwards and now lies over southwest Bay of Bengal and adjoining Sri Lanka with associated cyclonic circulation extending up to 7.6 km above mean sea level. It is likely to become more marked during the next 48 hours. Heavy rain is likely to occur at isolated places over north coastal Tamilnadu and Puducherry in the next 24 hours. These rains are likely to continue for three more days.”
While Chennai was predominantly dry during most part of the day yesterday, surprise rains blasted the city during the night as Nungambakkam recorded a massive 6.64 cm in the night itself. Meenambakkam too recorded 2.62 cm. ‘City’s maximum and minimum temperatures were 27.4 and 21.5 degrees Celsius which is a massive drop from normal by around 3 degrees.
As of now, a cool ambiance is prevailing with relative humidity hovering at the 90-95 per cent mark. In the next 24 hours, sky condition is likely to be generally cloudy. Few spells of rain or thundershowers, heavy at times is likely to occur,’ the official added.
Fishermen asked to stay safe
Due to the existence of the low pressure area, Met department officials said, strong winds at the speed of 15-20 knots will be blowing from northerly to northwesterly in the sea.
These wind speeds are likely to rise up to 25-30 knots occasionally. So, fishermen are advised to stay safe. In addition, the low pressure area is also blowing moist winds over the north Tamilnadu coasts.
Sunday evening blockbuster
Surprise rains blasted the city during the night as Nungambakkam recorded a massive 6.64 cm within few hours.
According to a forecast, the low pressure area over Bay of Bengal and adjoining Sri Lanka coast is likely to intensify in the next 24 hours.
Chennai will witness light rainfall activities in the day time while the intensity of rains is expected to pick up pace during the late evening and night hours. So, moderate to heavy rainfall activity may make an appearance over the city for another 24 to 48 hours.
