After drenching parts of Indonesia and taking a unique track across the Timor Sea with Cyclone Odette, Tropical Cyclone Seroja is bringing heavy rain and strong winds to Western Australia. Seroja strengthened into a Category 3 tropical cyclone on the Australian scale for a time early Sunday, local time. The storm packed 10-minute average sustained wind speeds of 120 km/h (75 mph) at its core as it churned just off the coast. Around 7:40 p.m., local time, Seroja made landfall along the coast of Western Australia between the towns of Geraldton and Kalbarri as a Category 3 cyclone. The very destructive core of Category 3 Severe Tropical #CycloneSeroja is crossing the coast now between Kalbarri and Gregory. Kalbarri recorded a 170 km/h wind gust at 7:03pm WST and has seen 111 mm of rain since 9am.

By late Sunday night, local time, Seroja was downgraded to a Category 2 cyclone as the interaction with land caused the storm to lose some wind intensity. Seroja will continue to lose some wind intensity into Monday morning before transitioning into a nontropical storm as it moves across the southern portion of Western Australia. Despite this transition, Seroja can bring areas of heavy rainfall and strong wind gusts. "Wind gusts can reach 80-115 km/h (about 50-70 mph) inland along the track of the storm," said AccuWeather Lead International Meteorologist Jason Nicholls, adding that this can lead to minor structural damage and additional power outages. "Seroja should be moving fast enough to avoid significant flooding," added Nicholls. Rainfall totals of 75-150 mm (3-6 inches) can still lead to localized flooding along the track of the storm. Seroja can also bring rough seas to the southern coast of Australia into the beginning of next week as the storm is absorbed by a nontropical system swirling over the Great Australian Bight.

(AccuWeather) Activity in the Timor Sea and eastern Indian Ocean began last weekend when a system emerged and eventually developed into Tropical Cyclone Seroja. Conditions were just right, with plenty of warm water and light to moderate wind shear, to the northwest of Australia for the tropical low northwest of Seroja to strengthen into Tropical Cyclone Odette on Friday morning, local time, as Seroja continued to gain wind strength.

Both tropical systems remained close to one another, with the eye of each cyclone perhaps only 800 km (500 miles) apart at times to end last week. With two tropical systems so close together, forecasters said a meteorological phenomenon known as the Fujiwhara effect occurred for a time on Friday. The Fujiwhara effect occurs when two tropical systems are close enough together, and strong enough, that they influence the track of the other, resulting in the two storms rotating around each other. "Seroja was the dominant feature, with the system formally known as Tropical Low Odette rotating in the clockwise fashion around Seroja," AccuWeather Meteorologist Mary Gilbert said. "This was the case for portions of the day on Friday and Saturday until Seroja absorbed the energy of former Odette later Saturday." When Cyclone Seroja formed over the weekend, tropical moisture inundated portions of Indonesia, causing deadly mudslides and flooding.
