For much of the month of March, the weather was stuck in a pattern dominated by high pressure centered over the western Atlantic. This meant that skies remained fair and there was little if any precipitation. However, this did not bode well for Bermuda continues to be in a significant drought with both hydrological and agricultural impacts. March 2012 ended as the driest March in the Bermuda Weather Service Records with only 0.79″ of rain being recorded. This is the third year in a row that Bermuda has seen unusually dry conditions at least in spring.
However, the pattern shifted as March ended and April began allowing a a series of strong winter-type storms to push into the area. The first storm came March 29th and 30th with gales and brought most of the month’s rain. The cold front associated with this storm did not push all the way through to usher in cooler drier air before the next storm developed and pulled the front northwards as a warm front.
The second storm was much more significant than the first. It brought strong gales to the island with storm force gusts. In fact, the winds from this storm were stronger than any previous storm this year, and the low pressure recorded in Bermuda with it was lower than with any previous storm this year at 995mb. This is very unusual as this type of storm typically only has the right conditions to develop in mid-late winter; by early spring the upper air patterns do not typically favor the intensification of extra-tropical storms in the Gulf Stream.
The April storm consisted of three parts:
However, despite producing severe winds, this second storm did bring some much needed rain to the island. Over an inch of rain was recorded at the Bermuda Weather Service over the first three days of April because of this storm system.
