In the Western North Atlantic there is a pretty well marked
region of not very low Low pressure. Whilst in the east the pressure
are more normal.

This flaccid pressure system has spread across the North Atlantic.

A deep low on the TLH of this map:

yesterday (1st April 08) spread out to cover half the northern neck of
the North Pacific by today (the 2nd.)

Is this indicative of further eruptions at Hawaii or is it a normal
characteristic of most Lows as they leave a continental land mass. The
pressure is still low 971mb but it was 954mb yesterday.
