Meanwhile, in a statement released by the India Meteorological Department in Bengaluru, the trough/wind discontinuity from southeast Madhya Pradesh to South Interior Karnataka (SIK), across Vidarbha, Marathawada and North Interior Karnataka (NIK) extending up to 1.5km above mean sea level persists.

But as per IMD, the department issued a severe heat (red) alert only when the actual maximum temperature crosses 47 degrees Celsius.

The maximum temperatures are likely to continue and also be around 40 to 46 degrees Celsius over parts of NIK districts, such as Raichur, Kalaburgi, Yadgir, Ballari and Vijayapura districts till 6 May, the natural disaster management centre said on social media platform X.

The remaining NIK districts, most of the SIK districts and Dakshina Kannada district are likely to experience maximum temperature between 40 and 44 degrees Celsius, it added.

Parts of Kodagu, Udupi, Hassan, Shivamogga, Chikkamagaluru and parts of Uttara Kannada districts are likely to experience between 33 and 40 degrees Celsius till 6 May, according to the centre. From 7 May, maximum temperatures are likely to come down by 2 to 3 degrees Celsius across the state, according to KSNDMC.
