Forecast for next two week
Weather systems & associated Precipitation during Week 1 (18 to 24 March, 2021) and Week 2 (25 to 31 March, 2021)
Rainfall for week 1: (18 to 24 March, 2021)
Cumulatively, above normal rainfall likely over northwest & adjoining central India and extreme south Peninsular India; normal to above normal over many parts of north Peninsular India. It is likely to be below normal over remaining parts of the country (Annexure V).
Rainfall for week 2: (25 to 31 March, 2021)
Due to absence of any active Western Disturbance, rainfall activity is likely to below normal over northern parts of the country. However due to trough/wind discontinuity at south Peninsular India, light to moderate rainfall with thunderstorm & lightening activity likely over south Peninsular India. Hence rainfall activity is likely to be normal to above normal over above area. It is likely to be below normal over remaining parts of the country (Annexure V).
Temperature for week 1 & 2: (18 to 31 March, 2021)
No significant change in maximum temperatures over rest parts of the country during week 1.
During week 2, due to likely dry weather over most parts of the country (outside south Peninsular India), the maximum temperatures are very likely to rise gradually over most parts of the country. Hence, normal to above normal maximum temperatures likely over northwest, east & northeast India. These are likely to be below normal by 2-3°C over south Peninsular & adjoining central India (Annexure VI).
