As the northeast monsoon sets in, the India Meteorological Department (IMD) has issued weather warnings across the state: heavy rainfall is forecast until October 29, with six districts under an orange alert for “heavy to very heavy” rainfall, while several others are under lower-level yellow alerts.
What the alerts mean
- An orange alert signifies that very heavy rainfall (typically 12 cm to 20 cm in 24hrs in isolated places) is likely and may lead to localised flooding, water-logging, traffic disruption or landslides.
- A yellow alert means heavy rainfall (7 cm to 11cm in 24hrs in isolated places) is possible and caution is advised.
- The IMD’s advisory suggests that the weather systems currently influencing the region will persist till around October 29.
Regions and districts at risk
According to reports:
- Coastal districts such as Dakshina Kannada and Udupi in Karnataka have been placed under orange alert for very heavy rainfall.
- Several districts in the interior and ghats region are also flagged under orange alert owing to the enhanced rainfall likely from low pressure systems in the Arabian Sea/Bay of Bengal.
- Some other districts are under yellow alert for thunderstorms, gusty winds and moderate to heavy rain.
Why the heavy rain forecast?
- The withdrawal of the southwest monsoon has been followed by the early onset of the northeast monsoon and the formation of low-pressure systems which enhance rainfall over the region.
- Coastal and ghats regions are especially vulnerable because of orographic lift (rainfall increases when moist winds hit hills) and proximity to sea-influenced weather systems.
What residents should do
- Avoid non-essential travel during periods of very heavy rainfall. Roads may get water-logged or damaged.
- Be alert to warnings from local disaster management / meteorological units.
- Fishermen and those venturing into the sea or along coast should heed advisories—coastal wind speeds may rise and seas may become rough.
- If you live in hilly or slope areas, be on the lookout for possible landslides or falling trees.
- Ensure that drainage channels are clear of debris in vulnerable areas to reduce flood risk.
- Charge mobile phones, keep emergency contact numbers handy, and store essential items in easily accessible places in case of sudden rainfall or flooding.
The heavy rain alert remains valid through October 29, after which weather conditions may begin to ease. However, the IMD indicates that until then, sporadic spells of intense rain are likely, especially in the flagged districts.
With the monsoon phase shifting gears and rainfall intensity expected to pick up, the orange alert for six districts is a clear signal to stay cautious and prepared. Being alert and following precautionary measures now can help avoid damage and ensure safety during this heightened rainfall period.
