Wet and Windy at times

October was another month of above average rainfall, at 8.72 inches. By mid October the average yearly rainfall of 55.50 inches had been surpassed. In the early part of the month, we enjoyed above average temperatures even though it was quite windy on a number of days. During the month, Leslie, Michael and Nadine passed by with little effect on Bermuda.

The month began windy, wet, and cloudy with a developing low pressure area to our southwest. The associated warm front lay just to the south of Bermuda. As it moved north it dropped over 2 inches of precipitation over the 1st and 2nd. Following this, high pressure moved into the area and brought a few dry days.

An area of disturbed weather moved off the Florida coast and was designated Sub-Tropical Depression One on the 4th. This disturbance slowly acquired more tropical characteristics, and was upgraded to Tropical Storm Leslie on the 5th. Leslie was predicted to track close to the west of Bermuda and a Tropical Storm watch and warning were issued early on the 6th. However, by evening, Leslie was downgraded to a tropical depression and moved by well to our northwest, with minimal effect on the Island.

On the 8th we had some showers, which produced just under an inch of precipitation. We had more rainfall on the 9th and 10th as a cold front approached and crossed the island early on the 10th, with a number of light showers of rain or drizzle.

There were a number of drier, cooler days following the cold front passage on the 10th, as a ridge of high pressure built over Bermuda. By the 14th a warm front associated with a low pressure area to the south, dropped almost ½ inch of rainfall. The front lingered in the area and brought thunderstorms and heavy showers on the 15th with close to 3 inches of precipitation, the highest daily rainfall amount recorded so far this year. The depression remained to our southwest and slowly took on tropical characteristics, strengthening and becoming Hurricane Michael on Tuesday the 17th. For the third time this year, a tropical system designated as a potential threat to the island moved by to the northwest without any damaging winds or seas. In fact, Bermuda was enjoying mostly sunny conditions as Michael moved by 200nm to the northwest on the 18th.

A further Tropical Storm, Nadine, formed to the southeast on the 20th and passed by well to the east on the 21st.

From the 23rd to the 28th Bermuda experienced showers and strong to gale force winds as a low deepened to our south and tracked northwards towards Nova Scotia. Conditions improved by the month end as the decreasing northwesterly winds brought cooler, drier air to the Island.
