As U.S. temperatures cool, tropical waters remain warm

Posted by Sheena Parveen under Daily updates

Many areas around the country are experiencing fall, with some parts of the U.S. experiencing blizzards from the strongest storm system to ever hit the Midwest.  An all-time record low pressure was reported of 28.20″ (954.9 mb) in Bigfork, Minnesota on October 26th.  Despite the cooler temperatures filtering into the U.S., tropical water temperatures are still on the warm side, conducive for tropical development.  Water temperatures are still in the mid 80’s in the Caribbean Sea, mid to low 80’s in the Gulf of Mexico, and near 80 degrees closer to Bermuda. 

A few tropical waves have formed and become better organized since 24 hours ago.  There is Invest 90L, Invest 91L, and Invest 92L.

Invest 90L is about 1200 miles NW of the Cape Verde Islands.  It is likely that gale force winds are occurring within this system; winds of 34 to 47 knots (39 to 54 mph).  There is a chance for this system to continue developing further.

No matter what the outcome of 90L, the system will be directed to the North as a cold front sweeps near and high pressure builds in to its West. 

Invest 91L is 1000 miles E/SE of the Windward Islands.  This system is currently very unorganized, but it does have the potential to slowly develop as it tracks to the W/NW.

Computer models move the storm through the Caribbean over the next several days, some models moving the storm farther North than others. 

Invest 92L is the most organized of them all so far.  An area of low pressure is forming in this system, and atmospheric conditions appear to be favorable over the next few days to form a subtropical or tropical depression.  92L is about 700 miles SE of Bermuda.

As with Invest 90L, a cold front will approach from the West and push this system North.  High pressure will also build in to the West of the cold front, keeping this system away from the U.S.
