Rainfall is expected in Guwahati beginning on Tuesday, September 24 according to the India Meteorological Department (IMD). This weather change coincides with a critical period, since the present heatwave is being exacerbated by Assam seeing its lowest rainfall in 75 years.
September is usually one of the warmest months of the year in the area, but according to meteorologists at the India Meteorological Department, this year’s heat wave is unique due to the duration and record-breaking temperatures.
Guwahati recorded a record-breaking 39.3 degrees Celsius on Monday, while Dibrugarh recorded 39.5, North Lakhimpur recorded 39.6, and Jorhat recorded 37.9. In all three sites, these were the highest September temperatures ever recorded. On Monday, Shillong had its highest-ever September temperature of 29.9 degrees, which it recorded for the third day in a row.
The Kamrup Metropolitan District Elementary Education Officer, who is in charge of Guwahati City, announced on Monday afternoon that all schools in the area would be closed for four days, from September 24 to 27, due to the excessive heat and rising temperatures. This decision was made in response to the unprecedented temperatures.
Many factors could be responsible for the high temperatures, according to a scientist at the Regional Meteorological Centre: “There is no moisture incursion from the Bay of Bengal due to the lack of any favourable synoptic condition, and the southwest monsoon is weak over the region.” Moreover, there is more insolation, or the quantity of solar radiation that reaches the Earth’s surface, because there have been primarily clear skies during the day. The region’s urbanisation and deforestation are two local variables that are causing the temperatures to rise overall.
However, the city is expected to see “few spells of rain or thundershowers” throughout the week, according to the latest prediction. Assam’s recent temperature was about 38 degrees Celsius.
Rain is predicted, which will bring respite to the residents from the heat after many days of extreme heat. Temperatures are forecast to drop by two to four degrees. The combination of two cyclonic circulations—one over the west central Bay of Bengal and the other over south coastal Myanmar—is what is responsible for the weather shift, according to IMD’s bulletin. Together, these systems have created a cyclonic circulation that is tilting southwestward across the Central Bay of Bengal, reaching up to 5.8 km above sea level.
It is expected to give rise to a low-pressure region in the next 24 hours, which may bring the season’s last burst of monsoon rains. As a result, Tuesday is expected to see an increase in rainfall, with September 25 and 26 expected to see stronger downpours.
