Tropical cyclone Genevieve began her life as a tropical depression in the eastern Pacific Ocean. As it crossed the 140W line of longitude, separating the eastern and central Pacific, this system weakened, and became a post-tropical cyclone for several days. Once the low level circulation center, or what was left of it, came into our central Pacific…the Central Pacific Hurricane Center (CPHC) began tracking it.
It became what we could call a tropical disturbance, as it was carried along in the low level trade wind flow. Recently it began to organize itself again, aided by light winds aloft , and warm sea water temperatures below. The CPHC upgraded it into a tropical depression…as it restrengthened. It’s now back to being referred to as Genevieve, and will likely intensify further over the next 12 hours…becoming tropical storm Genevieve for a day or two.
The good thing is that this system isn’t likely to turn northwestward towards the Hawaiian Islands. It’s expected to migrate along in a generally west to west-northwest direction. The long and short of all this is that our islands don’t have to worry about threatening weather conditions, other than some possible heavy showers with time. The northern fringe of its associated clouds will bring an increase in showers to our area later Thursday into Saturday, with improving weather as this system moves away to the southwest Sunday into early next week.
Here’s the CPHC graphical track map for this system, along with a satellite image…down to the southeast of the Big Island of Hawaii. Thereafter, it appears that there will be more tropical activity originating to our southeast and east-southeast through the next week, if not longer…we’ll need to keep an eye out in those directions.
