A Meteorological Bomb Will Hit Northern Vancouver Island On Tuesday

In meteorology we have a name for midlatitude storms that intensify explosively.  Such storms, known as meteorological bombs, occur when the central low pressure of a storm drops at least 24 hPa in twenty four hours.   (A hPa is a unit of pressure, also known as a millibar.)

The forecast models are now emphatic that such explosive development will occur tonight and tomorrow over the eastern Pacific, with the resulting intense low pressure center headed for the northern tip of Vancouver Island.

Take a look at the latest forecast for Tuesday at 11 AM shown below:  a 961 hPa low center! Wow.  

One of the deepest lows to approach our region in years.  Our typical low center dropx to around 990 hPa and the greatest storm of all...the Columbus Day Storm of 1962 was 955 hPa.   (note the figures shows sea level pressure, shown every 1 hPa)
