strong easterly winds brought rain and fog. The winds from the 

 easterly quadrant persisted for 30 hours and attained gale force for 

 8 hours. These winds were accompanied only by a slow drop in 

 pressure but no evidences of a real disturbance. Unfortunately no 

 pilot balloon observation could be obtained. The morning map of 

 April 24 showed a minor depression just east of the Bahamas. This 

 moved slowly northward deepening slightly and assuming more 

 definite characteristics as it moved until in the vicinity of Bermuda 

 it was found as a full fledged extra-tropical cyclone on the evening 

 map. From Bermuda it moved with surprising rapidity, averaging 

 50 miles an hour, and increasing intensity to a position just south of 

 Cape Race, Newfoundland, on the morning of April 25. It then 

 moved more slowly east and northeast, deepening steadily, and passed 

 just south of observation vessel's position on April 26. The observa- 

 tion vessel experienced winds of force 11 for 4 hours and winds of gale 

 force, 7 and over, for 29 hours. Lowest barometer 29 inches. As 

 this storm swept eastward it apparently increased in intensity and 

 area causing much damage to shipping as far east as the Irish coast. 

 Two known cases of serious distress were the direct result of this 

 storm. The S. S. San Quentin, whose case was handled by the S. S. 

 Washington and the S. S. Ivanhoe which was assisted by the S. S. 

 Pilsudsky. The great mass of polar air pouring down over the ocean 

 in the wake of this deep disturbance stagnated over the middle 

 Atlantic, intensifying the semipermanent high pressure over the 

 ocean and bringing regular early summer conditions to the Grand 

 Banks region, i. e. a prevalence of light to moderate southwest winds 

 bringing showers and fog. April was, in general, cold with an aver- 

 age temperature of 35.0° F. although the percentage of fog, visibility 

 less than 2 miles, was about normal, 22.1 percent. (See figs. 8 to 12.) 



MAY 



Regular early summer conditions persisted all through this month. 

 No storms of marked intensity passed through the area. Light to 

 moderate south and southwesterly winds prevailed with seasonably 

 warm and mild weather, and much fog. The percentage of tune with 

 visibility less than 2 miles during the last half of May was 57.0 per- 

 cent. The average temperature for the month was 45.3° F. and the 

 percentage of fog was 46.4 percent. (See figs. 12 to 16.) 



JUNE 



The observation vessel was present in the Grand Banks area only 

 during the first 9 days of June. During that period light to moderate 

 southwesterly winds persisted, bringing warm and very mild condi- 

 tions and much fog. The average temperature was 45.9° F. and the 

 percentage of fog, visibihty less than 2 miles, was 54.6 percent. (See 

 figs. 17 and 18.)
