The meteorological department issued a weather report stating a low-pressure area over the Bay of Bengal has intensified into a deep depression. This is expected to bring heavy rain to eight districts in North Tamil Nadu on August 31 and a yellow alert is issued.
What Is Deep Depression?
During the monsoon season, storms develop as warm ocean waters evaporate and form clouds. When this process continues at a specific location, a low-pressure area can develop into a depression. The present system, which has evolved into a deep depression, is moving toward Odisha.
In Tamil Nadu, no significant storms have occurred this year so far. The deep depression now poses a risk of heavy rainfall in eight North Tamil Nadu districts. In this case, Tiruvallur, Tirupur, Theni, and Tirunelveli received a yellow alert for August 31.
