JTWC直接評級Medium

AN AREA OF CONVECTION (INVEST 91S) HAS PERSISTED NEAR 10.5S
116.8E, APPROXIMATELY 549 NM NORTHWEST OF BROOME, AUSTRALIA. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN OBSCURED LOW LEVEL
CIRCULATION CENTER WITH DEFINED CONVECTIVE BANDING ALONG THE WESTERN
SEMICIRCLE. ENVIRONMENTAL ANALYSIS REVEALS A HIGHLY FAVORABLE
ENVIRONMENT FOR DEVELOPMENT WITH STRONG WESTWARD UPPER-LEVEL OUTFLOW,
LOW VERTICAL WIND SHEAR (10 TO 15 KTS), AND VERY WARM SEA SURFACE
TEMPERATURES (29 TO 30 C). GLOBAL MODELS AGREE ON 91S TRACKING
SOUTHEASTWARD AS IT CONTINUES TO DEVELOP OVER THE NEXT 24 TO 48
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS MEDIUM.

BoM升格澳式C1，命名Luana，預計12小時內將登陸西澳

Tropical Cyclone Luana to cross the northwest Kimberley coast today as a category 2 system.

Area affected
Warning zone
Broome to Kuri Bay, including Derby and adjacent inland areas.

Watch zone
Bidyadanga to Broome and adjacent inland area.

Cancelled zone
Between Kuri Bay and Mitchell Plateau.

At 5:00 am Australian Western Standard Time
At 5:00 am AWST

Intensity
category 1, sustained winds near the centre of 75 kilometres per hour with wind gusts to 100 kilometres per hour

Location
within 35 kilometres of 16.1 degrees South, 121.8 degrees East, 210 kilometres north northwest of Broome and 125 kilometres west northwest of Cape Leveque

Movement
east southeast at 22 kilometres per hour

Tropical Cyclone Luana has formed and is forecast to intensify to a category 2 system prior to making landfall on the northwest Kimberley coast later today. The most likely crossing location is between north of Broome and Cockatoo Island.

After landfall over the Dampier Peninsula, Luana may move back over the waters of King Sound where it is forecast to maintain category 2 intensity until making landfall again near Derby. It will weaken and be below tropical cyclone strength during Sunday morning after moving further inland.

Hazards

DESTRUCTIVE WIND GUSTS to 140 km/h may develop near the system centre between Beagle Bay and Cockatoo Island today as the system approaches and moves over the coast.

GALES with DAMAGING WIND GUSTS to 120 km/h are possible between Beagle Bay and Kuri Bay from early this morning. Gales may extend south to Derby and towards Broome this afternoon, and to adjacent inland areas overnight tonight. The risk of the system taking a track further west is decreasing, though if it does gales may extend from Broome to Bidyadanga later today.

HEAVY RAINFALL which may lead to FLASH FLOODING is possible for the northwest Kimberley district, including the coast and adjacent inland areas today.

Coastal residents within King Sound are specifically warned of the potential for a DANGEROUS STORM TIDE as the cyclone passes over the Sound. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING.

Tides will be higher than normal between Beagle Bay and Kuri Bay today and LARGE WAVES may produce MINOR FLOODING of low-lying coastal areas as the system crosses the coast.


Recommended action

Tropical Cyclone Luana has strengthened to category 2 and is crossing the Kimberley coast between Beagle Bay and Cape Leveque. Wind and rain impacts are occurring from north of Broome to Kuri Bay and are expected to extend south this evening and overnight.

Luana may remain near or move over the waters of King Sound tonight, and may maintain category 2 intensity until it is close to Derby. It will weaken below tropical cyclone strength during Sunday morning after moving further inland.

Hazards

DESTRUCTIVE WIND GUSTS to 130 km/h may occur near the system centre between Beagle Bay and Cockatoo Island today as the system moves further over land. These DESTRUCTIVE WIND GUSTS may extend to Derby tonight if the system maintains strength longer than forecast.

GALES with DAMAGING WIND GUSTS to 120 km/h currently extend from north of Broome to Kuri Bay. These gales may extend south to Derby and Broome this afternoon and evening, and to adjacent inland areas overnight tonight.

HEAVY RAINFALL which may lead to FLASH FLOODING is possible for the northwest Kimberley district, including the coast and adjacent inland areas today and Sunday.

Coastal residents within King Sound are specifically warned of the potential for a DANGEROUS STORM TIDE as the cyclone passes close to the Sound. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING.

Tides will be higher than normal between Beagle Bay and Kuri Bay today and LARGE WAVES may produce MINOR FLOODING of low-lying coastal areas as the system crosses the coast.

A separate Severe Weather Warning is current for peripheral areas in the Kimberley.
