Cyclone warning issued in northern Western Australia

A tropical low moving across the northwest of Western Australia could develop into a cyclone, the Australian Bureau of Meteorology warned on Monday.

In the warning zones were coastal areas in the Pilbara and Kimberley regions, approximately 2,200 km from Perth.

The system was 90 km southwest of Derby at 9:00 a.m. local time and moving southwest at a speed of 15 km an hour.

It was expected to move offshore later in the day and once over open water, possibly develop into a category one cyclone.

The Department of Fire and Emergency Services' Kimberley regional duty co-ordinator, Steven Longo, told The ABC on Monday a blue alert was in place for people in, near or between Kuri Bay and Exmouth.

A blue alert warns residents to "start preparing for cyclone weather."

"Our advice to those residents (is) just to get ready for some possibly dangerous weather conditions by preparing their home inside and out," Longo said.

"They can secure or remove some loose material from in and around the home and possibly ensure your emergency kit is complete and check your family knows what to do."

While category one would be of relatively low strength, coastal areas between Broome and Port Headland were advised that gale force winds of up to 100 km per hour could buffer the towns should the cyclone develop.

After weakening on Tuesday, the tropical system will continue to buffer the coast as it continues its path parallel to the Pilbara coast.

Depending on how close the system tracks to the coast, gales may continue into Tuesday evening.

Heavy rain and flood warnings have also been issued for the north and west of the Kimberley region.

Mount Hart, now in the wake of the system, received 122 mm at 9: 00 a.m. on Monday, while many other locations recorded falls above 25 mm. Endi
