According to Skymet Weather, these rains can be attributed to a trough running along the East Coast. It has increased the level of moisture in the atmosphere over the city. Due to this, convective clouds had formed leading to light rainfall over Chennai.
Now also, the weather conditions remain favorable for rain and thundershowers to continue over the city in the next 24 hours. However, the intensity of these showers will remain light only.
It is only after June 24, the state capital will witness some good showers. As per weathermen, Chennai may see light to moderate rain and thundershowers.
However, the weather will remain warm and humid in the coming days. These activities will be majorly recorded during the late afternoon or evening and thus will not have much impact over day maximums.
So far, Chennai has recorded 14.9 mm of rain as compared to monthly average of 55.9 mm. Being a rain shadow area, Tamil Nadu including Chennai does not record much rains during the Southwest Monsoon.
