Tropical Cyclone 11E (Karina) remains active in the northeast Pacific…located approximately 1325 miles east of Hilo, Hawaii – Tropical Storm
Tropical Cyclone 12E (Lowell) remains active in the northeastern Pacific…located approximately 905 miles west of the southern tip of Baja California – Tropical Storm
Tropical Cyclone 13E (Marie) is now active in the northeastern Pacific…located approximately 325 miles south of Zihuatanejo, Mexico – Tropical Storm
Here’s a good NASA satellite image of these three storms

Tropical Cyclone 11E (Karina) remains in place…although has strengthened during the past 12 hours
At the time of this writing, and based on NHC advisory #39, tropical storm Karina had maximum sustained winds near 70 mph, with higher gusts.
According to the NHC, satellite imagery shows that the cloud pattern of Karina has been improving during the past 6 hours, and a banding eye feature is becoming apparent in the most recent images. Beyond 48 hours, a weakening trend should begin due to TS Karina moving over a cooler sea surface, and the intrusion of a stable and dry air mass from the northwest.
The current motion is estimated to be northeastward. The computer models show that Lowell will continue to influence Karina…in moving in a northeastward to east-northeastward direction through the next three days. Thereafter, a weakening Lowell is expected to pass to the north and northwest of TS Karina. Karina will move towards the northwest and eventually toward the west by the end of the forecast period.
Here’s a satellite image of Karina…along with what the computer models are showing.
~~~ Tropical Cyclone 12E (Lowell) continues to be an extra large tropical storm…although has weakened during the past 24 hours
Wind speeds at the time of this advisory #19 were 60 mph sustained…with higher gusts.
According to the NHC, thunderstorm activity continues to gradually decrease around the large, ragged eye-like feature of Lowell. TS Lowell should continue to gradually weaken as it moves over cooler sea surface temperatures during the forecast period, and the cyclone should become a post-tropical low within two days…and a remnant low by 72 hours.
Lowell should continue moving generally northwestward during the next 48 hours. Thereafter, this weakening tropical cyclone should turn more west-northwestward as it begins its dissipating phase.

~~~ Tropical Cyclone 13E (Marie) is the newest tropical cyclone to form in the northeastern Pacific…not far offshore of the southern Mexican coast
Wind speeds at the time of this advisory #3 were 50 mph sustained…with higher gusts.
According to the NHC, TS Marie continues to become better organized, with abundant deep convection and banding features in all quadrants. Additionally, water vapor imagery shows that the upper-level outflow is becoming increasingly well defined.
Since this 13th tropical cyclone of the 2014 hurricane season will be moving under low wind shear, and over a very warm sea surface over the next several days…continued strengthening seems very likely.
TS Marie should become a hurricane within 24 hours, and will likely attain at least Category 3 status during the forecast period.

Finally, there continues to be a tropical disturbance in the central Pacific…although it has a low chance of developing
This area of disturbed weather continues to be of no threat to the Hawaiian Islands, despite its relatively close proximity to the southeast.

1.) Low pressure centered about 650 miles southeast of Hilo, Hawaii, is nearly stationary. Isolated thunderstorms are associated with the low, but are showing little sign of organization. Conditions are conducive for only limited development over the next two days.
* Formation chance through 48 hours, low, 10 percent.
