Lucinda 0300 local time:

73 kt, G 95 kt, 981.4

That is 10-min sustained winds? What was the lowest land pressure report?

Lucinda 0300 local time:

73 kt, G 95 kt, 981.4

That would be 0200 local time. 0300 local time is in 15 minutes.

Lucinda 0300 local time:

73 kt, G 95 kt, 981.4

That is 10-min sustained winds? What was the lowest land pressure report?

Lowest pressure reported at Lucinda was 977.3 hPa at 12:05 am local time. Bear in mind Lucinda is in the southern section of the storm but away from the eyewall and thus did not get an eye pass.

Lucinda 0300 local time:

73 kt, G 95 kt, 981.4

That is 10-min sustained winds? What was the lowest land pressure report?

good question! I thought it was 1-min but it's 10-min ... conversion is 10-min x 1.14 = 1-min, so 73 kt 10-min is 83 kt 1-min.

"Speed Knots Wind observations averaged over 10 minutes."

Lowest pressure I have seen was 977 reported also by Lucinda.

I'm going to check the WunderMap to see if any other data came out.

Doesn't appear to be an official BOM observation site, fwiw.
