confusedr as was the Gulf Stream front. Towards the end of the 

 month warm tongues extended east of the Gulf Stream at 30N and 

 33N^ perhaps precursors to cyclonic eddy activity. 



The number of storms was far below normal/' resembling a summer 

 month in the WNA. The storm tracks were concentrated north of 

 Nova Scotia with only one crossing the coast to the south. A 

 brief, severe e x t r at ropi ca I storm caused the loss of the drilling 

 rig Ocean Exeji^e^s while under tow in the Gulf of i-lexico. 



Ma^^ - Although almost the entire WNA area unoer consideration was 

 warmer this month/' the change was seasonal, and the warm SST 

 anomalies decreased in extent and intensity. An area of 

 anomalies east of the Gulf Stream from 3CN to 35N is a 

 consequence of increased cyclonic eddy activity. The 

 Mexico was almost entirely colder than normal with 

 anomalies only off Florida ano in the loop current area.

There were three small cyclonic eddies and one larger 

 anticyclonic eddy, broken from a large Gulf Stream meander on 

 10 May, present at the end of the month. The Gulf Stream flowed 

 smoothly to off Cape Charles, then began to meander downstream. 

 However, the meanders diminished in size as the month advanced. 

 The Slope Water/Shelf Water front was tortuous with incursions 

 and excursions north cf 37N. 



Again this month there were fewer storms, and these farther off 

 the coast and farther north, than usual. One e x t rat rop i ca I storm 

 developed in the central Gulf, crossed northern Florida, and then 

 followed the Gulf Stream across the Atlantic. 



June - The entire Atlantic area was 1 or 2 dec warmer than last 

 month, as expected for the season. Positive SST anomalies 

 diminished slightly, and -3.3C anomalies appeared off the mouth 

 of Chesapeake Bay. Negative anomalies were found southeast of 

 the Bay to east of the Gulf Stream and southeast of Nova Scotia. 

 The Gulf of Mexico was colder than normal over its entire area.
