Hot weather conditions will prevail over north and central India and warm conditions are very likely in a few areas of Madhya Pradesh, the Met Department had earlier said.

According to the IMD's prediction on distribution of rainfall this monsoon, the central India will get 'normal' rainfall but the southern Peninsula - Karnataka, Telangana, Andhra Pradesh, Tamil Nadu, Kerala and Puducherry - may get 'below normal' rainfall. The north-east India is expected to get least rainfall (below normal) during the period. The monthly rainfall over the country as whole is likely to be 101% of its Long Period Average (LPA) during July, and 94% of the LPA during August - both with a model error of plus or minus 9%. Anything between 90%-96% of the LPA is considered "below normal" while rainfall in the range of 96%-104% of the LPA is considered "normal." Also, rainfall is considered "deficient" if it ranges below 90% of the LPA, and "above normal" if it falls between 104%-110% cent of the LPA. Above 110% of the LPA is considered "excess" rainfall.
