I was listening to the radio (Radio 4) this morning about the hurricane that hit Portugal, the first in centuries, >100mph winds causing devastation, speculation that it was going to head down to Morrocco and cause devastion on the way etc. I got out of bed and looked at the weather charts:

expecting to see a tightly wound ring of isobars over the Iberian peninsula but there was nothing! Ok, when you look at the charts now it has all gone but when I looked this morning I had the range of charts from Friday to Tuesday and there was nothing there.
How can you have a hurricane and it not show on the weather map?
Was it fake news? (just joking).
 
It is a bit mysterious. NOAA had Leslie making landfall around Lisbon yesterday as a tropical storm. I've just left my boat N of Porto and was more than a little concerned but there seems no evidence of even gale force winds in the area.

With no energy source it weakened rapidly, what's left is over France by the looks of it. Saturdays gribs showed similar, rapidly filling.

It had weakened a lot before it even got to the coast, still a nasty one though, hundreds of thousands without power. Peak gusts of over 100mph recorded, somewhere....

It hit further up. The models seemed to struggle keeping track of it, already it had been running back and forwards around the Atlantic since Sept. 23 , even saturday morning gfs had it hitting the Algarve, luckily it didn't but there was still a extreme band of rain and wind went through in the early hours.

On Passageweather the GFS and WRF were widely different. GFS was showing an unpleasant large purple area heading for Lisbon, whereas WRF was showing a much lesser depression with little more than 40kn even about 12hrs before it approached land.

I am not doubting that it happened. I am asking how could it have happened without there being any record of it on the synoptic charts?

It was on the synoptics, just filled very quickly after landfall, and was weakening anyway. Still packed a punch when it landed though.
