Monty made landfall in a large, sparsely populated region of the Pilbara, Western Australia.

On February 29, a buoy 10 nautical miles away from the center of Monty reported mean winds of 92 mph (80 knots, 148 kmh).

Low wind shear of less than 10 knots allowed for development until Monty made landfall as a category 3 storm.

As Monty moved forwards inland, it began to rapidly weaken and speed up but still caused major flooding in Pilbara.

The town of Pannawonica was cut off by flood waters, Maitland's bridge was washed away at the North West Coastal Highway.
