Storm timeline
During warmer summer months, low-level surface troughs typically cross Australia's west coast, which often leads to the development of isolated lightning storms in inland Western Australia, occasionally reaching the shore (as on December 20, 2009, when a storm developed south of Perth and gave the city of Mandurah 2.8 millimeters (0.11 in) of rain for that month). However, on 21 and 22 March 2010, high dew and high surface temperature combined with low to west of WA caused a rare northern wind to occur. This means that the storm formed will be pushed southward, not the normal eastern pattern.

A storm formed in the Geraldton region in the afternoon, ending the fourth longest dry spell in the city, with 14.6 millimeters (0.57 inches) of recorded rainfall in Geraldton. The town of Badgingarra (halfway between Perth and Geraldton) bore the storm burden for two days, receiving 27.6 millimeters (1.09 inches). The storm also flourished in the interior of Gascoyne, where Cue received more than 80 millimeters (3.1 inches) rainfall and Magnet Mountain received 57 millimeters (2.2 inches).

Hurricane Geraldton moved towards the beach in the morning, passing Perth, but not before ending the nearby Mandurah dry season with 2.4 millimeters (0.09 in) of rainfall and then Bunbury where 9 millimeters (0.35 inches) fell. Seven fires at the poles cut electricity to 1,200 homes in both cities.
The severe thunderstorm warning was then announced for the middle western region (around Geraldton), lower west (including the city of Perth and Mandurah), the center of Wheatbelt, Great Southern and Gascoyne area south of Western Australia at 09.45.

Hailstones with a diameter of 3-5 cm are reported around the suburbs such as Osborne Park, Nollamara and Craigie, while hailing as high as 6 cm (2.4 inches) is measured on the outskirts of Perth's western part of Wembley.
At 4 pm, Perth storms have reached the southern edge and strong winds have been reported on the outskirts of Jandakot (96 km/h). Jarrahdale, southeast of Perth, receives 44.2 millimeters (1.74 inches) in half an hour, exceeding the conditions required to flood 1 in 100 years within 15 to 30 minutes. However, the storm begins to diminish in intensity and becomes larger, forming a multi-squall line as it moves further south. A second wave of storm activity thrived behind the first set, giving it a further fall north of Perth. Around 4.30 pm, a severe lightning warning was issued to Mandurah and surrounding areas.
