00:00Severe tropical cyclone Sean. Currently a Category 3 system is impacting parts of
00:06the Pilbara Coast with damaging winds and heavy rainfall and we can see that
00:10clearly here on the radar image with widespread heavy rain and thunderstorm
00:14activity along parts of the Pilbara Coast and we can also see the eye of the
00:19cyclone well off the coast and that's continuing to track towards the west
00:23southwest but many of the Pilbara Coast overnight and earlier this morning saw
00:27widespread heavy rainfall and damaging winds we can see that on our
00:31observations with many areas experiencing winds in excess of 100
00:35kilometers an hour that includes around the Karratha area where we saw gut winds
00:39gusting to 107 kilometers an hour last night but we also saw very heavy rainfall
00:44there as well with a fall of 270 millimeters in the 24 hours to 9 a.m.
00:50Western Standard Time but we also saw widespread 50 to 150 millimeter falls as
00:55well through parts of the Pilbara Coast and that's been leading to flash flash
00:59and isolated river flooding as well but what is a cyclone doing right now well
01:04we currently have a Category 3 system sitting off the coast and cyclone
01:08warnings are current between Mardi and Ningaloo and that does include the
01:12communities of Exmouth and Onslow and we expect it to continue moving towards the
01:17west southwest possibly intensifying into a Category 4 system as we get into
01:21overnight hours before weakening again as we move into day on Tuesday but note
01:26it is well away from the WA coast and we should see conditions easing tonight but
01:32we still have to get through the late morning and afternoon period this
01:35afternoon and this evening so what does that look like in more detail well we're
01:39still likely to see widespread rain and thunderstorm activity continuing to
01:43stream on the coast as it all wraps around the cyclone offshore but as we
01:47move into the afternoon evening hours we should see a slow contraction of this
01:51weather towards the west clearing from the east and slowly contracting towards
01:56the Capes as we move into Monday night and Tuesday morning and while it might
02:00be an intense Category 4 system off the coast conditions will be easing along
02:04coastal areas but still windy with gusty winds and also showers and
02:08thunderstorms likely but then as we move into Tuesday night conditions should
02:12really start easing through northwestern parts of WA but the cyclone will
02:16continue to remain well off the WA coast. Now we're also likely to see an
02:21additional 50 to 100 millimetres through those coastal areas of the Pilbara with
02:25isolated falls in excess of 100 millimetres possible particularly about
02:29some of our offshore islands and around the northwest Cape and because of that
02:34we could also have flood watches current that means if you live in these
02:38highlighted areas particularly on coastal areas additional forecast
02:41rainfall could lead to flash and riverine flooding. So quickly to
02:46reiterate cyclone warnings current from Mardi to Ningaloo including the
02:50communities of Exmouth and Onslow for heavy rainfall and damaging winds that
02:54could bring down trees and power lines and rainfall could lead to flash and
02:58riverine flooding and possible inundation of homes properties and
03:01businesses. So if you live in this highlighted area or know someone that
03:04does make sure you stay up to date the latest forecasts and warnings by our
03:08website app and social media and listen to all and any advice from your local
03:13emergency services.
