Cloudy skies, moderate fog expected in Delhi on Republic Day
Overcast conditions are predicted in Delhi on Republic Day and moderate fog is expected to lower visibility levels to 200 metres.
"The maximum and minimum temperatures are likely to settle around 9 degrees Celsius and 19 degrees Celsius, respectively," the India Meteorological Department said.
"Moderate fog is likely in the city on Thursday morning. Cloudy conditions will prevail during the day," an official said.
According to the weather office, 'very dense' fog is when visibility is between 0 and 50 metres, 51 and 200 metres is 'dense', 201 and 500 metres 'moderate', and 501 and 1,000 metres 'shallow'.
Delhi witnessed overcast skies and logged a minimum temperature of 10.6 degrees Celsius, five notches above normal, on Wednesday.
The maximum temperature settled at 19.3 degrees Celsius, two notches below normal.
The Safdarjung Observatory, Delhi's primary weather station, had logged a minimum temperature of 12.3 degrees Celsius, the highest this month so far, on Tuesday.
The maximum temperature had settled at 21.6 degrees Celsius.
The city had recorded a maximum temperature of 25.9 degrees Celsius on Monday -- the highest in the month in four years -- according to the weather department.
Clouds trap heat that gets through during the day, keeping night-time temperatures above normal.
However, cloudy weather reduces daytime temperatures by preventing exposure to the sun.
Delhi is likely to see cloudy skies for the next four to five days.
A fresh western disturbance may lead to light rainfall on January 29, it said. Delhi has not recorded any rainfall this winter season so far. The Met department attributed it to the lack of strong western disturbances in November and December.
Last year, the city had recorded 82.2 mm rainfall in January, the highest in the month since 1901. The capital logged eight cold wave days in January this year, the most in the month in 15 years. It saw seven cold wave days in January 2020 while it did not record any such day last year.
The city recorded two intense coldwave spells -- from January 16 to January 18 and January 5 to 9, according to IMD data.
It, however, did not record any cold days. Delhi has also logged over 50 hours of dense fog this month so far, the highest since 2019.
