GUWAHATI: South west monsoon is expected to cover the entire Northeast in the next couple of days, even as average daytime temperatures in most cities show an upward trend in the first 10 days of June, sources at the Regional Meteorology Centre at Borjhar here confirmed.
“Movement of moisture-laden winds towards the Northeast has been restricted to an extent causing a delay in the complete onset of south west monsoon over the region and also pushing up mercury levels,” an RMC source told The Shillong Times on Sunday.
Daytime temperatures in Guwahati and Shillong, for instance, have risen by almost six and four degrees Celsius since June 1.
Maximum temperature here on Sunday was recorded the highest in the month so far at 38.4 degrees Celsius as against 38.3 degrees Celsius on Saturday.
Shillong recorded a maximum temperature of 26.7 degrees Celsius on Sunday as against 26.4 degrees Celsius on Saturday. “Shillong did witness rain at 2.30pm on Sunday though,” the source said.
Comparitively, Guwahati recorded a maximum temperature of 32.6 degrees Celsius on June 1 while Shillong recorded 22.7 degrees Celsius.
According to reports, the advance of south west monsoon is being prevented by a cyclonic circulation over the South China Sea.
“But this system over South China Sea is expected to move away in a northeastward direction and moisture-laden winds can trigger rainfall over the region in the coming days. In fact Shillong and Cherrapunjee did receive 5mm and 19.8mm rainfall respectively till 5.30pm on Sunday,” the official said.
Till date, south west monsoon has covered Nagaland, Manipur, Mizoram, Tripura and parts of Assam and Arunachal Pradesh even as the met bulletin on Sunday warned of heavy to very heavy rain at isolated places over Mizoram Nagaland, Manipur and Tripura, Meghalaya and Assam over the next two days.
