Invest 97L RGB September 29th 2014 1545UTC
RGB satellite imagery at about 12:45pm local time today showing the low to our near west. Convection has waned since last night, but could recover later this afternoon bringing more showers and thunderstorms.

Another mesoscale low formed near Bermuda on Sunday. This low slowly organized near the island bringing isolated to scattered showers and thunderstorms into the area for much of the day on Sunday. The low then passed near or over parts of the island overnight Sunday into Monday dumping more than an inch and a half of rain with isolated wind gusts over gale force in areas exposed to easterly winds.

The low level structure of this low can be seen on Bermuda Weather Service radar and the beginnings of the rain band associated with the waterspout can be seen forming to the east of the island here at around 8:30am.

Banding features have developed around this small increasingly organized low, and these have the potential to become squally with a chance for waterspouts. One such waterspout was observed at the Bermuda Weather Service to the east of the airport at 9:45am local time. See the Bermuda Weather Service Facebook Page for more information on that.

At 9am local time this morning, the National Hurricane Center gave this disturbance a 30% chance of become a subtropical depression in the next 48hours before environmental conditions become too unfavorable for additional organization and development. The Bermuda Weather Service is monitoring this low very closely in conjunction with the National Hurricane Center and are including advisories and special weather statements to cover the associated potential for adverse weather impacting the island.
