currents the former enter the gulf through the yucatan channel and under certain barometric and planetary conditions pass by the western end of cuba and flow out through the straits of florida or else under converse planetary and atmospheric conditions they spread out over the gulf in all directions moving on its center the shore currents owe their origin to the prevailing southeast winds and they flow northward along the western extremity of the gulf and west along the northern boundary meeting near galveston to form a stream current which flows in a southeasterly direction toward the straits
