As meteorological patterns evolve over the Indian subcontinent, a notable trough in easterly at mean sea level has been identified, stretching from Sri Lanka to the Southwest and adjoining Westcentral Bay of Bengal. This atmospheric phenomenon is set to influence the weather conditions in the region, particularly over Tamil Nadu and Kerala, as well as parts of Coastal Andhra Pradesh and South Interior Karnataka.
At the upper air levels, a Cyclonic Circulation has established itself over the Comorin area, accompanied by another in the lower tropospheric levels off the Tamil Nadu coast in the Southwest Bay of Bengal. These dual circulations are anticipated to instigate changes in precipitation patterns, leading to a series of weather events across the southern parts of India.
Expected Weather Conditions:
- Tamil Nadu and Kerala (21st – 25th November 2023): Light to moderate rainfall is highly likely in many areas, with isolated instances of heavy rainfall. Residents are advised to be cautious and prepared for potential downpours. On the 22nd and 23rd of November, 2023, isolated very heavy rainfall is predicted, requiring heightened awareness.
- Coastal Andhra Pradesh (21st November 2023): Anticipate light to moderate rainfall, creating wet conditions across coastal regions on the 21st of November. While the intensity may not be as high as in the southern states, residents should stay vigilant.
- South Interior Karnataka (22nd – 25th November 2023): Prepare for light to moderate rainfall during this period. Though not as intense as in Tamil Nadu and Kerala, it is advisable to stay updated on local weather reports.
General Weather:
For the rest of the country, no significant weather changes are expected during this period. While the southern regions brace for potential heavy rainfall, the central and northern parts can expect relatively stable weather conditions.
As with any weather forecast, it is crucial to stay tuned to updates from official meteorological sources for the latest information. Communities in the affected areas are urged to take necessary precautions to mitigate the impact of heavy rainfall, including potential flooding and related hazards.
