龙卷风警告，今天早上8点多发布的。
大家关心的应该是这段：
FLOODING of LOW LYING COASTAL AREAS is possible in
Geographe Bay. HEAVY RAINFALL is also possible on the southern side of the
system with LOCALISED FLOODING. Extensive flooding is not expected.
地势低的海岸线地区可能会有洪水（海边也叫洪水不？），这里指的是Geographe Bay。龙卷风区域的南部会有暴雨，有可能当地会有洪水，预计不会蔓延。

TROPICAL CYCLONE ADVICE NUMBER 41
Issued at 8:58 am WST on Saturday 29 January 2011
CYCLONE BIANCA MAY IMPACT COMMUNITIES IN THE SOUTH WEST OF WESTERN AUSTRALIA ON
SUNDAY
Bianca will be rapidly weakening as it approaches the coast on Sunday. However
there is uncertainty about how fast it will be moving at that time. Therefore
there is some risk that Bianca could still have an impact on the South West of
WA. So people should prepare for:
. DAMAGING WINDS with gusts to 100 kilometres per hour
. ROUGH SEAS and DANGEROUS SURF CONDITIONS
. COASTAL EROSION and FLOODING OF LOW LYING COASTAL AREAS
. SEVERE to EXTREME FIRE DANGERS
. HEAVY RAINFALL south of the cyclone with possible LOCALISED FLOODING.
A Cyclone WARNING has been declared for coastal areas from Jurien Bay to
Albany, including Perth, Mandurah, Bunbury and Busselton.
At 8:00 am WST Severe Tropical Cyclone Bianca, Category 3 was estimated to be
920 kilometres west northwest of Perth and
680 kilometres west northwest of Geraldton and
moving south at 24 kilometres per hour.
Bianca is expected to weaken further during today and begin to move towards the
southwest corner of the state. As it approaches the coast it will weaken
rapidly but there is some risk that Bianca could still have an impact on the
South West on Sunday. DAMAGING WINDS with gusts to 100 kilometres per hour are
possible southwest of a line Jurien Bay to Albany.
Tides between Jurien Bay and Cape Naturaliste will be higher than expected and
may rise above the highest astronomical tide level with ROUGH SEAS, DANGEROUS
SURF and COASTAL EROSION. FLOODING of LOW LYING COASTAL AREAS is possible in
Geographe Bay. HEAVY RAINFALL is also possible on the southern side of the
system with LOCALISED FLOODING. Extensive flooding is not expected.
VERY HIGH to SEVERE FIRE DANGERS are likely near the west coast on Sunday,
possibly reaching EXTREME across inland areas south of a line from Geraldton to
Leonora to Israelite Bay on Sunday.
FESA State Emergency Service (SES) advises that people should start planning
for bad weather and listen for further advice.
Details of Severe Tropical Cyclone Bianca at 8:00 am WST:
.Centre located near...... 27.5 degrees South 107.8 degrees East
