MONTHLY FORECASTS. 127 



movement of the Gulf Stream and the Southward extension of Ice brought 

 down by the Labrador Current. Icebergs and field-ice may be encoun- 

 tered as far South as the 4:3rd parallel, between the 4:6th and 50th 

 meridians. 



June. — Generally fair weather will prevail, with occasional gales along 

 the transatlantic route and oflf the Atlantic coast of the United States. 

 West Indian Hurricanes which occur as early as June originate, generally 

 speaking, in lower latitudes than later in the season, and are most liable 

 to recurve in the belt from latitude 20° to 23° N. Considerable Fog will 

 be encountered off the Grand Banks and the coast to the Westward as far 

 South as Hatteras, and also in the vicinity of the British Isles. Icebergs 

 and some field-ice may be encountered between the Grand Banks and the 

 45th meridian, as far South as the 4:3rd parallel. 



July. — Generally fair weather wiU prevail. Occasional moderate gales, 

 frequently accompanied by electric phenomena, will be felt North of the 

 40th parallel ; and West Indian Hurricanes are apt to occur, especially 

 during the latter part of the month. Frequent Fogs may be expected 

 over the Grand Banks, off the American coasts North of Hatteras, as well 

 as in mid-ocean, along the transatlantic route. Icebergs may be encoun- 

 tered to the Southward and Eastward of the Grand Banks, possibly as far 

 South as the 41st parallel. 



August. — Fair and exceptionally fine weather may be expected generally 

 over the Atlantic this month. The principal danger will be from Hurri- 

 canes, and navigators should watch carefully to avoid them, if possible, or 

 at least meet them to the best advantage. August, it should be remem- 

 bered, is the principal Hurricane month. (Full directions are given in the 

 Section deahng with them, for the best action to be taken on encountering 

 one of these dangerous storms). There will be considerable Fog over and 

 Westward of the Newfoundland Banks, as far as the American coast, but 

 it will be less frequently met vnth than during July. Only a few bergs 

 and little or no field-ice will be encountered off the Grand Banks. 



September. — Moderate or fair weather may be expected, with occasional 

 gales North of the 35th parallel and between the coast of the United 

 States and Bermuda. West Indian Hurricanes are very likely to occur, 

 and should be prepared for. There will be less Fog along the trans- 

 atlantic steamship routes, and little or no Ice will be encountered off the 

 Grand Banks. 



October. — Generally moderate weather will prevail, but gales may be 

 experienced along the transatlantic route and off the American coast three 

 or four times during the month. Although October is the last month of 

 the West Indian Hurricane season, several of the most severe Hurricanes 

 on record have occurred about this time, and no precaution should be 

 neglected. It will be well to remember that October Hurricanes recurve 

 in lower latitudes, generally speaking, than during July and August. There 

 will be less Fog than during September, and no Ice will be encountered 

 South of the latitude of Cape Eace. 



November. — The West Indian Hurricane season is now at an end, and 

 the gales that are encountered with increasing frequency North of the 40th 

 parallel are mostly from the Westward and North- Westward. During the
