IMD is at the centre of criticisms for failing to forecast Thursday’s brought 201. 2mm and 148. 9mm of rain in Nungambakkam and Meenambakkam respectively.

On Friday, IMD officials explained that the previous day’s spell was due to sudden and fast movement of an easterly trough (an elongated region of low pressure) from Bay of Bengal to the city which the ground and satellite-based observation instruments failed to pick up.

The trough, which was originally expected to bring heavy rainfall to districts south of Chennai on Friday, carried rain-bearing clouds with it. These clouds stationed over the city bringing continuous heavy spells. The city, which already recorded 9% excess rainfall during the June-September season (500. 2mm), has added 1360. 4mm of rain this northeast monsoon (October-December) season against a normal of 784mm. This is an an excess of 74%, officials said. The state received 59% excess rain this year.

N Puviarasan, director, Area Cyclone Warning Centre, IMD, told TOI the easterly trough extending from south to north Tamil Nadu led to formation of clouds that moved over the city coast and remained stationary. The movement of the easterly trough and the clouds was supported by a westerly trough above it at an altitude of 10km.

“On the eastern side of this trough, there was convergence and on the western side there was divergence. The convergence caused the formation of clouds. The trough and clouds moved fast over the city coast bringing steady heavy spells. None of the ground or satellite observations were able to pick this up,” he said.

The IMD said a dense network of ground-based instruments may improve forecast accuracy but it may still be difficult to forecast the intensity of rainfall over specific locations.

For the next 48 hours, IMD has forecast thunderstorms with heavy to very heavy rainfall at one or two places in the city. Skymet Weather, in its online post, said heavy rainfall may continue over the city till January 1 and may reduce by January 2 and 3.

With Several Areas Of Chennai Still Water-Logged, Experts Suggest Stormwater Drain Network Needs A Complete Rethink

The chaos on city roads continued on Friday with traffic snarls everywhere. The rain eased overnight, but the effects of Thursday’s cloudburst remained.

Roads were either damaged or flooded, and vehicles crawled through one lane, avoiding the stagnant rainwater.

Traffic cops were missing on many arterial roads. The result: traffic jams even during non peak hours.

Anna Salai and Saidapet witnessed huge jams during the morning and evening peak hours. The vehicles moved at a snail’s pace on Poonamallee high road, Santhome high road, portions of Dr Radhakrishnan Salai, Mandaiveli road, Choolai main road, De Mellows Road, Perambur Barracks Road, BB Road in Perambur, Paper Mills Road.

Vehicles plying towards Poonamallee from Porur piled up for at least two kilometres as people began leaving the city to celebrate New Year. Inward traffic was relatively less.

Vehicles also crawled on several arterial roads such as Eldams Road and T T K Road in Alwarpet, Khader Nawaz Khan Road in Nungambakkam, Rajamannar Road in K K Nagar, K P Dasan Road in Teynampet, Thirumalaipillai Road, Bazullah Road and Prakasam Road in T Nagar, and Sivagami Road in Perambur.

“It is water-logged everywhere and we were trying our best to streamline the traffic in the available space,” said a senior police officer.

Even though the Greater Chennai Corporation had at least three weeks in December to desilt the storm water drains, not much was done.

While officials said the city has not witnessed such a high single-day rainfall even in November, the reason for inundation was primarily because of silt-blockage and poor gradient of drains, say experts.

An independent study done by GIS expert Dhayanand Krishnan in T Nagar found that six crore litres of water is generated for 10 cm rain in 0. 7 square kilometers. “To carry this much water, the drains must be built in a uniform way from start to end. But it is not so. Drains are in various sizes across the stretch,” he said.

Krishnan said that the rains had stopped by midnight on Thursday but water did not drain even by Friday morning. The city had 271 spots with severe inundation. Of these, 44 were in Kodambakkam zone  and 42 in Royapuram

zone.

A civic official said 279 pumps had been deployed across the city, some of them in action even  on Friday evening.

There are 2014 RT-PCR labs, 941 TrueNat, 132 CBNAAT and 30 others. There are more than 200 manufacturers of RT-PCR test kits while 53 are making rapid antigen kits. A total of seven home-testing RATs should be available soon and daily testing capacity is in excess of 20 lakh, said official sources.

Official sources said that the health ministry was working closely with national scientific establishments and the states to ensure that facilties for detection, tracing and medical care are available keeping in mind the lessons learnt from the second wave.

States have been asked to ensure the Rs 23,000 crore allotted for upgrade of medical facilities are utilised to the extent possible and beds with oxygen support and those in ICUs are augmented as well as even spread up in urban and semi-urban areas. So far, the need for medical attention in rural areas has been on the lower side.

After reporting highest single-day spike in Omicron cases for two consecutive days, India on Friday recorded lesser number of infections with Maharashtra, which had been leading the spurt for the last two days, reporting just four cases.

India reported 168 cases on Friday — lower than 263 on Thursday and 215 on Wednesday — taking the country’s total tally to 1,379. While Maharashtra just reported four cases, a sharp fall from 198 the previous day, Delhi led the states in single-day tally with 57 cases. Kerala was second with 44 cases while Haryana and Karnataka recorded 23 cases each, Gujarat 16 and Andhra Pradesh  1.

Maharashtra continues to lead the states in overall tally with 454 cases, followed by Delhi (320 cases), Gujarat (113) and Kerala (107). All other states have cases in double or single digits. With 44 cases, Kerala reported its highest single day tally so far. Health minister Veena George said no community spread of the new variant has been reported. The cases reported in the state include 52 people who came from low-risk countries, 41 from high-risk countries and 14 who came into contact with these people.

Besides Kerala, Gujarat was the other state to cross the 100-mark on Friday.

In Karnataka, of the 23 fresh cases, 19 had international travel history. The rest four had no travel history, but one of them was a contact of an Omicron-infected person.

Daily Covid-19 cases have doubled within 48 hours in both Maharashtra and Mumbai. The state reported 8,067 fresh cases on Friday as against 3,900 on Wednesday, and Mumbai saw 5,428 cases as compared to Wednesday’s 2,445.

State health officials have declared that the third wave — most likely to be dubbed the Omicron-Covid wave — has already begun in Maharashtra. “The state is at the doorstep of a possible lockdown. It is only a matter of time before strict restrictions will be brought back,” said relief and rehabilitation minister Vijay Wadettiwar.

With the rapid near-doubling of cases, the state public health department has estimated that active cases in Maharashtra will rise to 2 lakh by the third week of January. As of Friday, there are 24,509 active cases in Maharashtra. Active cases in the state increased three-fold between December 21 (7,093) and December 31 (24,509). In Mumbai, too, 2,061 active cases ballooned to 16,441 in the 10-day period.

In a letter to the state public health team, additional state chief secretary (health) Pradeep Vyas on Friday said, “Covid-19 cases, including the Omicron variant, are increasing and the third Covid wave has already started in the state. ” All districts have been asked to start prepara- tions to manage the patient load of the third wave.

“The number of Covid infections in the third wave is going to be huge,” said Dr Vyas. “Even if 1% case fatality is presumed, we can still land up with 80,000 deaths if there are 80 lakh Covid cases. ”

He warned people against getting “lulled by narrative” that the third Covid-Omicron wave is mild, and not fatal. “It is equally fa- tal for those who are not vaccinated and have comorbidities. So please improve vaccination coverage and save lives,” Vyas added

The daily positivity rate in the state and Mumbai continued to see a rise. With 1. 2 lakh tests conducted in the state in 24 hours, the positivity rate rose to 6. 5% on Friday. Mumbai’s positivity rate soared to double digits — 11. 4%.

With the cases galloping since the last 10 days, the city’s total December tally has surged over three times, while the state has reported an over 50% surge. In December, Mumbai reported 21,581 cases as against 6,827 cases in November, while the state added 43,759 cases this month as against 26,491cases in November. However, the only positive so far is that Covid-related fatalities in Maharashtra and Mumbai have witnessed a decline. On Friday, the state reported eight deaths, including one in the city. Mumbai added 48 deaths this month as against 89 deaths in November.

India finished 2021 well short of the target of fully vaccinating the entire adult population by year-end, announced in May. However, over 90% of the target population has received one dose and about 64% have been fully vaccinated as of 7 pm on Friday. Himachal Pradesh is the only state which has fully vaccinated its entire population while Punjab has the smallest proportion of fully-vaccinated population, just over 40%.

A total of over 145 crore doses of vaccine have been administered and the Centre said over 16. 9 crore doses were lying with the states as of Friday morning. Thus the vaccines supplied to the states (150 crore) or administered by private hospitals adds up to about 86% of the 188 crore doses required to fully vaccinate the total adult population estimated to be about nearly 94 crore.

Only 69% of those above 60 years, the most vulnerable population, has been fully vaccinated. Almost 73% of those in the 45 to 59 age group have been fully vaccinated, while a little over 55% of the 18-44 age group has received both shots. Among health workers, who constituted the first priority group to get the vaccines, 97 lakh have been fully vaccinated, while just over 1 crore have received one dose. Among frontline workers, 1. 8 crore have received the first dose and about 1. 7 crore have been fully vaccinated.

Barring Bihar, Punjab and Jharkhand, all states have administered the first dose to well over 80% of the popula- tion over 18 years. Punjab, Jharkhand and Uttar Pradesh have not fully vaccinated even half the eligible population. In the South, Tamil Nadu continues to be the laggard state, where just 86% have got the first shot and only 58% have been fully vaccinated.

Serum Institute’s Covishield accounts for 128. 9 crore doses or about 89%, while Covaxin accounts for 15. 7 crore (11%), other vaccines having made a negligible contribution so far. The demand for vaccines is likely to shoot up with children to be vaccinated from January 3 and booster doses to be administered from January 10.
