Sebastien forms - not a threat
Another one of those "tropical enough to be called tropical" storms formed northeast of the Caribbean Islands. Tropical Storm Sebastien is forecast to move into the central Atlantic and be absorbed by an approaching cold front.
This brings the hurricane season total to 18 named storms, higher than the predictions. But, a number of the named-storms this season had short lifespans, and were not of consequence. So when you add up the total tropical energy this year - the so-called ACE - it comes out very near the average prediction of the prominent forecasters.
