A mutiple Low system in the North Atlantic breeds a Blocking High not
a Blocking Low. My mistake. Notice the number of adjacent amtching

And with the Anticyclone over Britain the increase in Japanese quakes.

So now I am expecting a rather large earthquake -probably today or the
day after tomorrow because of the ac tivity already going on:

5.2 M. 2013/02/21 14:05.
29.2 N. 142.2 E. IZU ISLANDS, JAPAN REGION

5.8 M. 2013/02/20 21:23
18.6 N. 103.9 W. OFFSHORE COLIMA, MEXICO

Chile to Venezuela and The Aleutian Islands should be getting a lot of
tremors with that Colima one.
http://earthquake.usgs.gov/earthquak...quakes_all.php check how many smaller quakes showed up on the NEIC list.

And look at the stuff getting through from Africa on he
http://www.bom.gov.au/australia/char...Refresh+ View

That Izu Islands quake (Japan) is one of a series that is going to
extend quite far (with smaller stuff like the Vanuatu quake
intervening from the Fijian Triangle.)

That should be interesting to watch. The anticyclone over Britain
tends to play havoc with my seismic aspirations but only to delay
expectations. Great Expectations tend to increase with any ddelay. It
could be delayed for a few weeks and turn into something really nasty
when the tropical storms all fade away.

No tornadoes to speak of... well... isolated stuff; nothing like the
fierce spells that could have been (so far.)
So be careful.
