New Depression # 9 plus loss of Arctic Ice

NHC is watching two areas in the Tropics. One is a depression, the ninth of the season, and the other a low in the Far Eastern Atlantic with a good chance for growth.

Tropical Depression #9
Is roughly 1200 miles East of the Lesser Antilles. Top winds as of this posting are at 30 mph and it is moving slowly to the NNW at around 8 mph.

Its not looking too healthy on satellite imagery. Strong upper winds are impacting it already and most of the rain is to the east of the center. This feature may not last too long.

Most models keep this depression over the open waters of the Atlantic. NO Worries for Us or the Lesser Antilles.



There is another broad area of low pressure near the Cape Verde islands which continues to get its act together.

Its roughly 400 miles SW of the Cape Verde Islands.

Over the next few days, the atmosphere surrounding this low will become favorable for growth.

It could become a depression/storm over the next 5 days.

This is what NHC is saying about it:

They are giving it  an 80% chance for development over the next 5 days. Even if it develops, models here too keep it as a worry only for the shipping lanes. 

The models project its path almost following
the footsteps of TD #9.

No worries for the islands, nor for us
here is South Florida.


Meanwhile, we are losing Arctic Ice very fast. A new NOAA reports a record loss coming in, in 4th place among the worst ice losses since the 70's.

This is their update:

Scientists report (today, 9-15-2015) that the Arctic sea ice summertime minimum is 4th lowest on record.
 #1.  Analysis of satellite data by NASA and the National Snow and Ice Data Center indicates that the accelerated summer melting trend since the late 1970s continues.
 #2.  This increased melting is a response to the warming global temperatures.
 #3.  It is unclear whether this year's strong El Niño has had any impact on the Arctic sea ice.
Tag:  Weather and climate researchers are continuing to study the possible effects of 
the increased open Arctic waters in the autumn might have on jet stream patterns over the United States and snow storm development in the winter season.

  1. Nice article Phil. What are your possible weather projections for the changing weather for us here in SE Florida with the current open water Arctic conditions?

  2. El Niño will dominate through early next spring at least. Looking at a wetter and hopefully cooler winter. As for the Arctic , only time will tell.
