The U.K. Meteorological (UKMET) office reports that a current storm is the strongest September storm on record in Britain since 1981.
The barometric pressure fell to 973mb at one point, which the UKMET office says was "unusually deep for September..." The last time they had such a strong storm in the month was back in 1981.
To put this into perspective, the pressure only fell to 975.4mb at New Haven during the height of Tropical Storm Irene last year. A pressure of 973mb is usually attributed to a hurricane, but in some cases, can be found in a mid-latitude cyclone. The interesting thing to note here is that September storms this strong are unusual.
Although the storm is not tropical in nature, it is still quite powerful. The area can expect strong winds, cooler than normal temperatures and significant precipitation.
The map above shows 500mb height anomalies (on top) and there are some major below normal anomalies. This is combined with a strong block over the northern Atlantic, which may lead to unsettled weather here in the northeastern United States over the next several days.
The lower half of the image shows sea-level pressure.
