According to the India Meteorological Department (IMD). Strong lower level Southerly/ Southwesterly winds from the Bay of Bengal to Northeast India are extremely likely to cause a moisture incursion from October 18 to 21, 2021.
Temperature likely to drop
From October 18 onwards, broad to widespread rainfall activity with isolated heavy to very heavy falls is highly likely over the northeast region due to its effect.
Due to the forecast rainfall activity, the daily maximum temperature in the North Eastern States is highly likely to drop from Monday onwards, according to the IMD data.
Impact Of rainfall
– Due to heavy rain, vision may be reduced on occasion.
– Low-lying locations are prone to flooding.
– Landslides/landslips with a specific location.
– Flash floods are a possibility.
– Temporary traffic disruption due to road waterlogging, resulting in increased travel time.
– Due to extremely heavy rainfall, kutcha roads have been damaged.
– Potential for damage to vulnerable structures as a result of Extremely Heavy Rainfall.
– People and cattle in open areas may be injured by lightning.
Steps advised to be taken
• If there are any traffic advisories given, follow them.
• Avoid going to regions where there is a lot of water logging or landslides.
• Stay away from invulnerable structures.
• Keep yourself up to date.
Hottest October across North-East
Summer appeared to have “encroached” on autumn’s territory, resulting in one of the hottest Octobers in the last 50 years in the northeast.
The India Meteorological Department (IMD) has forecast a few spells of rain or thundershowers in the coming days to help cool things down.
Guwahati had an average temperature of 37.07°C for three days until October 16, while most cities in the northeast had temperatures that were 4-5 degrees above normal.
Itanagar the hottest
On October 16, Itanagar, the capital of Arunachal Pradesh, recorded the highest temperature of 37.8°C, followed by Agartala, the capital of Tripura, at 34.8°C, Aizawl, the capital of Mizoram, at 29.2°C, Imphal, the capital of Manipur, at 28.8°C, Kohima, the capital of Nagaland, at 26.5°C, and Shillong, the capital of Meghalaya,
According to IMD officials, a day or two in October could have been hotter in the previous 50 years, but the high temperature has lasted abnormally long this time.
“The temperature rise is due to a low-pressure system in the Bay of Bengal. There is less moisture because of the low pressure, resulting in this dry weather,” said Sunit Das, a meteorologist at the IMD’s Regional Meteorological Centre.
“But the temperature is set to go down with rain or thundershower likely in the next three-four days,” he said.
According to the IMD, Assam had a monsoon with a 22 percent rainfall shortfall. In the other six adjoining north-eastern states, the rainfall shortfall varied from 21 to 30 percent.
The meteorologists said it would be difficult to attribute the dip in rainfall and an “extended summer” to climate change. “Data of all the meteorological centers over a substantial period need to be analyzed to conclude,” a weather specialist said.
On October 14, Guwahati, the Northeast’s gateway, saw the hottest day of the year.
Guwahati, the city, and its suburbs recorded the new highest maximum temperature (37.7°C) for October, according to the Regional Meteorological Center (October 14th, 2021). The previous high temperature was 37.0°C (1st October 2009).
A MET official said, “The daylight heat has witnessed a spike mainly due to climate change, deforestation, and an overall change in the lifestyle of the people in general”.
