In a span of 24 hours, from 8.30 on Sunday, Lucknow in Central Uttar Pradesh received 54 mm of rain, Fursatganj and Bahraich received a whopping 358 mm and 315 mm of rain respectively. Gorakhpur in east Uttar Pradesh also received 15 mm of rain.
In the next 24 hours we can expect some rain in west U.P, particularly in Bareilly and Moradabad, due to the low pressure lying over the region. Thereafter (in next 48 hours) the system will move from west to east along the foothills, giving good rain here. Though, the system will weaken during this time, it will continue to be seen as a cyclonic circulation.
The circulation will later cover Sub Himalayan West Bengal and Northeast India, giving good amounts of rain in the region. Northeast India at the moment is observing subdued rainfall activity, which is expected to increase once the cyclonic circulation reaches the region.
