Yellow Alert for Heavy Rain in South India, Delhi Air Quality Worsens
Imagine the sky is playing a game with different weather.
In the southern parts of India, like Tamil Nadu and Andhra Pradesh, the sky is getting ready to drop a lot of rain, with thunder and lightning, so a warning called a 'yellow alert' has been issued.
Meanwhile, in Delhi, the air is becoming a bit dusty and smoky, like a thin cloud of smog is covering the city.
This smog is making the air quality 'poor,' and it's expected to get even more 'very poor' in the coming days.
So, while some places are getting ready for a big rain shower, others are dealing with hazy air.
IMD has issued a yellow alert for heavy rain and thunderstorms in Tamil Nadu, Andhra Pradesh, and most of Karnataka.
Southern India typically receives significant rainfall during the final months of the year.
Delhi woke up to a hazy morning with smog, and an AQI of 278 in the 'poor' category.
Delhi's air quality is forecasted to deteriorate into the 'very poor' category between November 6 and 8.
The weather forecast for southern India indicates a mixed pattern with continued rainfall in southern and northeastern states.
