'TAIL-END OF A WILLY-WILLY.'

The West Australian, 4 April, 1912

THE STORM AT PORT HEDLAND.
CONDITIONS OH MARCH 20.
CAPTAIN ALLEN'S FEARS.

Port Hedland, April 3.

As if to palliate the tedium of the scorching, 
enervating heat Port Hedland was visited 
on March 20 with the tail-end of a
willy-willy which coming with equinoctial
tides, did a fair amount of damage. It was
fairly certain that had it been a full willy-
willy it would have spelt disaster to the low
lands of Hedland. 

Confirming that Port Hedland was only subjected to the outer fringe of the cyclone - centre 50+ miles away in the vicinity of Balla Balla. Note that the excessive heat was a precursor to cyclonic activity. 

It started on Tuesday night with a strong 
easterly wind, and the waves thundered on 
the beach with indications of heavier and 
deadlier surges out at sea. 

It simply cannot be argued that those at Port Hedland were unaware of a cyclonic system in the region prior to 20 March (Wednesday).

Wednesday morning saw about forty
luggers running to shelter off Port Hedland,
where they were soon safely anchored. These
luggers had a rough time on Tuesday night
near Turtle Island, and the cutting away of
masts in some cases was seriously 
contemplated. The wind increased its velocity, 
and it continued for three days and nights. The
waves surged up the harbour's entrance, and
the breakers crashed into the sandy Esplanade, 
and washed thousands of tons of it away.

Confirmation of physical warnings.

Captain Allen, of the Koombana, seemed
disinclined to go out, and when he decided
to do so he said, "I am going straight out to
sea, and will be lucky if I get to Broome on
Saturday." She left the port at half-past
10 o'clock on March 20 with propeller 
beating out of the water. When passing 
the entrance to the harbour she rolled 
deeply. 

Consistent with the ground swell out at sea and very light condition.

Captain Allen stated that he would fill the 
ballast tanks when he crossed the outer bank.
The ship headed due north, and was followed 
about an hour afterwards by the Bullarra
going south.

It took more than 2 hours to 'fill' the ballast tanks. In this report Bullarra followed an hour later (incorrect).

The damage done to the railway line on
the Causeway will cost a good deal to repair. 
The Esplanade suffered most, being washed 
away to the allotment boundaries in several 
places; in fact, the Esplanade has disappeared, 
and in its place we now have a sloping sandy 
beach from the rear of the Resident Magistrate's 
residence right round to the jetty. The light tower 
and oil house were undermined, while the roadway 
connected with the town bridge was rendered
unsafe for vehicular traffic. One lugger in port 
anchored too far in the stream, and drifted onto 
rocks. She was only slightly damaged. The 
schooner Alto was also damaged at the jetty.

Damage sustained at Port Hedland related to the storm surge and rain rather than hurricane-force winds.
It was a left-handed circular cyclone, and
from the directions of the wind it is certain
that the Koombana could not possibly have
avoided getting right into the centre. 

The centre of the cyclone was to the southwest of Port Hedland, whereas Koombana was headed northeast. This is not saying much about her 3,000 ihp!

The Koombana would be abeam Bedout at 4
p.m. on Wednesday, but out of course to the
south. 

Speculation: meaning Koombana would have been averaging 11.75 knots. Captain Allen had said that it was unlikely he would make Broome by the spring tide the following day, implying that he was anticipating less than 10.5 knots (strong headwind) and delays filling tanks. Out of course to the south of Bedout Island is strange - if anything, with a prevailing NE gale, out of course to the west makes more sense.

The wind was then blowing from
the east, but at 10 p.m. it changed from 
east to east north-east, and back in quick 
succession. At 10 a.m. on Thursday it was 
still blowing from the east, at noon east-north-east, 
and at 1 p.m. in the same direction. 

Confirmation that the cyclone stalled when it hit land (Balla Balla), but did not lose intensity.

It shifted at 2 p.m. to north-east, and 
remained in that direction till 6 p.m.. At 
10 p.m. it was blowing north-north-east, 
and at midnight it was north. 

Finally the system moved southeastward inland towards Marble Bar.

When Hedland got the worst of the hurricane 
on the 22nd, the wind was from the north-north-west 
from 4 a.m. till noon.

Three days later, and when Koombana was long gone to a watery grave.

The general congratulations possessing
people's minds on having escaped the full
force of the willy-willy in Hedland on top
of the equinoctial tides gave place to feelings
of horror when the tidings came that the
Koombana and all aboard were lost.

There must surely have been those who wondered why Koombana foundered steaming steadily away from the cyclone rather than into it, and, with this in mind, why the aging Bullarra escaped intact after steaming directly into the heart of the cyclone?
