The weather station at Palam gauged 61 mm precipitation on July 18. More than 65 mm precipitation at any place is considered heavy rain. Palawat said a combination of weather systems leads to heavy showers. “Heavy rains take place when a western disturbance, cyclonic circulation, easterly winds from the Bay of Bengal or southwesterly winds from the Arabian Sea combine with the monsoon trough,” he explained.
