Past Cyclones that affected Mumbai
Mumbai Cyclones are very very rare, very rarely we see cyclone making landfall as Cyclonic Storm in Kerala or Karnataka or Maharashtra. We can note down them and even memorize them. Have gone through the archives and found that two significant cyclones (1940 & 1948) that crossed near / over Mumbai. And have taken Nisarga too for comparative analysis of windspeeds.
1. 1940 Bombay Cyclone – Was the first cyclone to cross Bombay
Period October 12-16, 1940. The cyclone crossed right over Mumbai is the strongest cyclone Mumbai has faced till 1948 cyclone came. The maximum sustained winds (MSW) was 97 km/hr (60 miles/hr) while the gusts was 121 km/hr (75 miles/hr) over Colaba station. This was the 1st cyclone to cross Mumbai as a severe cyclone in recorded history. Colaba recorded 76 mm rainfall on October 16, 1940.
Maximum Sustained winds – Colaba  97 km/hr
Gusts – Colaba 121 km/hr
2. 1948 Bombay Cyclone – Strongest ever Mumbai cyclone
The 2nd cyclone Bombay saw was in 1948, just 8 years after the 1st one. It crossed 45 miles of Mumbai but the winds were felt more severe over Bombay with Juhu getting gusts of 151 km/hr and Colaba had gusts of 129 km/hr. The winds and damage were more than the 1940 Bombay Cyclone. Colaba recorded 101 mm rainfall on November 22, 1948. 47 people manning the SS Dipavathi drowned in the sea. Bombay came to standstill for 2 days. Dahanu got 257 mm rainfall while Lonvala 254 mm, Devgad 241 mm on 22.11.1948 while Matheran got 221 mm and Vade 231 mm on 23.11.1948

Back to Back cyclones for the west coast and this time the landfall area is far from Mumbai but the cyclone eye wall went 100 km from Mumbai city.
Maximum Sustained winds – Colaba 102 km/hr (today)
The wind speed of 114 km/hr recorded today at the weather station based at Afghan Church in south Mumbai’s Colaba area, Brihanmumbai Municipal Corporation (BMC) needs to be checked whether it is a 3 min average maximum sustained wind (MSW) or a gust.

Huge improvement in Dam Levels of Tamil Nadu, Mettur will get steady inflow henceforth

August 19, 2020

As you can see from the Dam levels in last week of July 2020, there has has been huge improvement in most of the dams with most dams in Coimbatore reaching full level. Mettur is close to 70% full and with all 4 dams in Cauvery basin in Karnataka being 100% full, all the excess water will be coming steadily to Mettur Dam in the coming days.

Mullaperiyar Dam level created little bit of panic, but rains subsided right on time and there is no need to panic on the Dam levels again for the time being. The water from Periyar Dam will be transferred to Vaigai Dam. Steady increase in Vagai Dam can be expected in next one month.

With dry days ahead, there will not be much to expect in the dam levels in the next two weeks. The Then Pennai basin dams of Sathanur and Krishnagiri are a worry, September and October are key month for them. Hope there is some improvement seen there.

Chennai combined levels are one of the best considering August with monsoon ahead, we are rightly placed. Even a 80% of monsoon rains can be good improvement to levels in Chennai lakes.

Next Active Spell of rains for Kerala, Cauvery Catchment and Western Ghats might start in around Mid-September. Till then rains will happen here and there with occasional isolated heavy rains.

Note: In case the picture is not clear, please save the image and open it in gallery and zoom and see it.

Rains expected again in Delta & South TN in next 2 days, All Time January Rains for Tamil Nadu is under threat

January 20, 2021

Well the North East Monsoon type rains will continue for next 2 days with an UAC located in SW bay and pushing convergence in the north will seen over Central Coastal Tamil Nadu to South Tamil Nadu particularly in parts of  Delta region (Nagapattinam, Tiruvaraur, Thanjavur)  and South Tamil Nadu regions (Ramanthapuram, Sivagangai, Pudukottai, Nellai, Thenkasi Kanyakumari, Thoothukudi) and even other nearby areas.

Reason for rains

There is an Upper Air Circulation (UAC) in South West of Sri Lanka and as  a result the convergence of easterlies are happening over North East Sri Lanka and Delta to South TN coast. Typical monsoon rains.

Good Rains are expected in next 2 days in Nagai, Thanjavur & Tiruvarur districts and moderate rains in Tuty, Ramanathapuram, Nellai, Kanyakumari, Thoothukudi, Pudukukottai, Cuddalore, Thenkasi, etc. Light rains are possible in Nilgiris and Coimbatore district too.

Is this the last rains for the month ?

No No, we already informed that monsoon will extend into February this year and more rains will start from month end around January 29/30, 2021. Breaks in North east monsoon are common. So there will be break in rains from 22nd January only to start again in 29/30th January. So the all time record rainfall in January is going to be broken for sure.
