Heavy Rainfall and Thunderstorms to Lash Southern India: Weekly Weather Outlook (May 18–24)

Monsoon Advances with Thunderstorms and Heavy Rainfall Across Southern India: Weekly Outlook

As the monsoon currents gradually build up strength, Southern India is set to experience an active weather spell in the coming week. Regions across Kerala, Karnataka, Tamil Nadu, Andhra Pradesh, and the Union Territories of Puducherry and Lakshadweep are likely to witness significant rainfall activity, with varying intensities and widespread impact.

Widespread Thunderstorms with Gusty Winds

A fairly widespread to widespread spell of light to moderate rainfall, accompanied by thunderstorms, lightning, and gusty winds reaching speeds of 30–50 kmph, is expected over Kerala, Mahe, Lakshadweep, and Karnataka. This surge in activity indicates a strong pre-monsoon presence, often characterized by rapid cloud buildup and sudden downpours.

Simultaneously, a scattered to fairly widespread pattern of similar weather is likely over Tamil Nadu, Puducherry & Karaikal, Coastal Andhra Pradesh & Yanam, Rayalaseema, and Telangana, making it a wet and stormy week ahead for these regions.

Isolated Heavy Rainfall Events

Isolated heavy rainfall is anticipated across various districts:

• Tamil Nadu, Puducherry & Karaikal: May 18th to 20th

• Kerala & Mahe, Coastal Karnataka, and North Interior Karnataka: May 18th to 24th

• Lakshadweep: On May 19th

• Coastal Andhra Pradesh & Yanam: May 20th to 22nd

• Rayalaseema: May 18th to 20th

• South Interior Karnataka: May 18th to 21st

These downpours could lead to localized waterlogging, especially in urban and low-lying areas.

Very Heavy Rainfall in Isolated Pockets

Even more intense rainfall is expected in isolated very heavy spells over:

• Coastal Karnataka: May 20th to 22nd

• South Interior Karnataka: May 18th to 20th

• North Interior Karnataka: May 19th to 22nd

• Ghats region of Tamil Nadu: May 20th

This could lead to landslides in hilly areas and potential flash floods in vulnerable zones. Travelers and residents are advised to stay alert and avoid unnecessary movement during heavy downpour periods.

What This Means

The incoming week’s forecast underscores a classic monsoon buildup. With gusty winds and scattered thunderstorms likely to persist, farmers and planners should remain cautious, especially those working in agriculture or outdoor operations. The convergence of moisture from the Arabian Sea and Bay of Bengal is fueling this system, preparing the ground for the onset of the southwest monsoon in the coming weeks.

Safety Tips During Thunderstorms:

• Avoid open fields and stay indoors when thunder rumbles.

• Unplug electronic devices during lightning storms.

• Watch for updates from local authorities and weather bulletins.

• Ensure proper drainage around homes to prevent waterlogging.
