India Met Department (IMD) has assessed as low probability of heat wave unfolding over major parts of the country during the next fortnight ending April 10. But mercury may hover around 38- to 40 deg Celsius over the plains of North-West India, Central and adjoining North Peninsular regions covering mainly Maharashtra, Madhya Pradesh, Gujarat and Rajasthan.

No major change

In its detailed two-week outlook, the IMD said maximum day temperatures may look up by 2- to 3 deg Celsius over North-West and East India over the next three to four days and no major change thereafter. No significant change in maximum temperatures is indicated over the remaining parts of the country during the week ending April 3.

Overall, these are likely to be below normal over the Central and Interior Peninsular India and North-East and adjoining East while being near- or slightly above normal over the rest the country during the week. During week 2 (April 4 to 10), the IMD saw no significant changes overall in maximum temperatures as compared with the previous seek. Maximum day temperatures may range between 38- to 40 deg Celsius over Central India, above normal by 2- to 3 deg Celsius over parts of North-West India and Odisha and below normal over the rest of the country.

As for rainfall, western disturbances would continue to drop isolated to scattered rain/snow over Jammu & Kashmir and Himachal Pradesh and isolated rains over North-West India until Saturday. A helpful trough and confluence of winds would bring isolated rain/thunderstorm to Coastal Andhra Pradesh, Telangana, Chhattisgarh, Vidarbha, Odisha, Jharkhand, Bihar and Bengal until Wednesday.

Rainfall outlook

Scattered to fairly widespread rain/thundershower may lash most of the North-Eastern States during many days of the first week ending as on Wednesday. As for the South, isolated rain/thunderstorm may break out over Tamil Nadu, Kerala and Interior Karnataka on many days of this week, the IMD outlook said.

Overall rainfall activity may stay above normal for North-East and adjoining East India; below normal for the hills of North-West India and Kerala; and near-normal over rest of the country during the week. During week two (April 4 to 10), the IMD sees the probability for rainfall to scale up over East and adjoining North-East India due to wind confluence at lower levels.

The overall rainfall activity is likely to be above normal over East and adjoining North-East India and near-normal for the rest of the country. The outlook comes on the back of the the 2019 pre-monsoon season as on date (March 1 to 27), leaving a deficit of 36 per cent for the country as a whole.

The deficit was worst in South Peninsula (65 per cent), followed by North-West India (44 per cent); East and North-East India (26 per cent); and Central India (10 per cent, considered normal).
