In our Tropical Kitchen this morning Lowell and Karina are now just remnant lows off the Baja west coast.  Hurricane Marie has been plutoed again to a tropical storm and expected to further downgrade to a post tropical depression later today.


The long range models are still showing nothing tropical popping up through the end of the month.


Tropical Waves:  one more emerged from the African coast yesterday so we now have four in transit in the mid Atlantic this morning.

This is sort of nurdy stuff. Most cruisers just want to know, when, where, how big, and where can I hide if a hurricane or tropical storm is in the hood.

Sea Surface Temperatures (SSTs)

Ocean temperatures greater than 26.5 °C (80 °F) through a depth of at least 50 metres (160 ft) are generally favorable for the formation and sustaining of tropical cyclones. Generally the higher the SST, the stronger the storm and greater chance of genesis. However, there are many factors affecting the strength of such storms. For Baja and the Mexican Riviera the SSTs become favorable about August.

Remotely sensed SST can be used to detect the surface temperature signature due to hurricanes. In general, an SST cooling is observed after the passing of a hurricane primarily as the result of mixed layer deepening and surface heat losses.
