The second attempt at a tropical system has taken place over the past several days in the Atlantic.National hurricane center at one point and time even classified this system with a code red thinking it would develop. Taking into consideration the above normal waters was probably what led them to think that this could develop into something stronger. Joe Bastardi also thought this would become the first named system of 2010. What happened?
Invest 92 L is a perfect example of what shear, dry air and a TUTT can do to a developing system.
You will often see Real Wx Services talking about and posting the current shear and SAL maps because these two things can have a hindering effect on tropical systems.
92 L was different in the sense that it developed much further south at like 6 N but that was just another indicator that this system from Day 1 in combination with the shear, dry air and TUTT did not have a chance at developing into anything other then a weak tropical wave.
Invest 92 L developing when it did is NOT an indicator of an active season, just as 92 L dissipating is not an indicator on a inactive hurricane season.
I have been stressing the need for a bermuda ridge needed to set up in place. This has not happened yet. Every time there has been an attempt a strong trough with an attending cold front has come thru into the NE. Until that occurs things will be a bit on the slow side.
Currently looking at the 2nd half of July beginning of August for this to occur. Until then expectation is for slow tropical season on the side of the Atlantic!
