Mumbai city and the konkan coast was lashed by heavy rains on S
Winds from the Arabian Sea rushing into the Bay Low, pushed moisture and rain clouds into the Maharashtra coast. As mentioned, the winds picked up really fast after the forming of the low. And rains commenced in the city early

By Tuesday, system would have crossed Gujarat, with a tendency to move back into the Arabian Sea.It would not be out of place to expect some rains on Tuesday, (when the system will re-emerge),along the Karachi coast.
