TROPICAL STORM JERRY TRAPPED IN HORSE LATITUDES

It’s called a Fish Storm because it’s in the Mid-Atlantic and no threat to land. The Horse Latitudes is the location of the subtropical belt of high pressure where atmospheric wind currents are often light and variable. To the north of the high pressure storms motions are influenced by the prevailing westerlies. To the south of the high pressure the tropical easterlies or trade winds steer storms towards the west.

If there’s a break in the high pressure belt, storms in the tropics can move northward by a trough of low pressure. Even though JERRY will continue over ocean waters, conditions are NOT FAVORAble for JERRY to become a hurricane.

UPDATE Tuesday October 1: By the weekend the westerlies will have dipped into the mid Atlantic Horse Latitudes to sweep Tropical Storm JERRY rapidly northeastward towards the Azores Islands.
