A gathering of Lows now fills the NE North Atlantic. The weather in
Britain is exactly as it was at the start of the spell I stated at the
outside, it would be so like. A dull overcast that requires one puts a
light on at mid day if one wishes to make a major repair to an engine,
or whatever, on one's kitchen table.

(As one does. Buggrit!)

I have just been looking at the chart for the day the British tourists
were killed in Spain in a rain-storm:
The Low was little less than 1016 mb at its lowest. Hardly any
different from an High.

Norbert is crossing the Mexican Baja peninsula. Something unknown
makes them turn about when they leave the tropics. Or does it?

If so, is it the same impetus that forces more northerly storms ashore
in the same direction? Or is it no force at all, just that the effort
they spend in going west ends when they stop building?

In which case, as they stop building they'd decrease in intensity
would they not?
