Rainfall activity over Gujarat Region
Specially south Gujarat region got heavy to very heavy rainfall. The reason for this rainfall was formation of cyclonic circulation over south Gujarat coast on 26th June. This is a very common development in the monsoon advancement season.
The Position of East-West Trough
The east-west trough position played a vital role in giving rainfall distribution (shown in picture below). The east-west trough is same as monsoon trough. But since the monsoon is not set all over India, it is called as east-west trough.
