Track of TD 14L

In the late morning of September 25, Lisa (14L)lost its hurricane status and weakened to a tropical storm. Following its northward forecast track as predicted, Lisa continued to slowly weaken further over the far eastern Atlantic near Cape Verde throughout the rest of the day.

On September 26, Lisa weakened to a tropical depression and became a remnant low several hours later, sooner than expected. At 5:00 PM AST (21:00 UTC), the center of the remnant low of Lisa was located near latitude 26.1 north, longitude 29.4 west.

The low is moving toward the north-northwest near 7 mph (11 km/hr), and this general motion is expected to continue for the next couple of days.

Maximum sustained winds are near 30 mph (45 km/hr) with higher gusts. Some weakening is expected during the next couple of days. Estimated minimum central pressure is 1008 mb (29.77 inches).

Remnant Low of TS Gaston (09L) Could Become New Tropical Storm

Shower and thunderstorm activity has become better organized in association with the remnant low of Tropical Storm Gaston (09L), located about 700 miles east of the Leeward Islands.

Environmental conditions appear conducive for tropical cyclone formation, and the low could redevelop into a tropical depression at any time today as it moves westward near 15 mph.

There is a high chance (80 percent) of this system becoming a tropical cyclone again during the next 48 hours.

Interests in the leeward islands should monitor the progress of this system.  Warnings will likely be required for some of these islands if advisories are re-initiated.

Tropical Depression Erika Weakens to a Remnant Low

Track of Erika

At 11:00 PM AST (0300 UTC), the center of the remnant low associated with former Tropical Depression Erika was located about 115 miles (185 km) south-southeast of San Juan, Puerto Rico and about 220 miles (360 km) southeast of Punta Cana in the Dominican Republic. Here, the coast of Venezuela can be seen south of the low.

The low is moving toward the west near 7 mph (11 km/hr). A gradual turn to the west-northwest and northwest is expected on Friday.

Maximum sustained winds are near 30 mph (45 km/hr) with higher gusts in a few squalls. The low is forecast to dissipate in a day or so. Estimated minimum central pressure is 1009 mb (29.80 inches).

The remnants of Erika are expected to produce total rainfall accumulations of 2 to 4 inches over the central and northern Lesser Antilles, Puerto Rico, and the US and British Virgin Islands, with isolated maximum amounts of 6 inches possible.

Blanca Dissipates, New System Forms

As Tropical Storm Blanca (03E) dissipates off the western coast of Mexico, a new contestant has already begun preparing to come into play: an area of low pressure located about 900 miles south of the southern tip of Baja California continues to show signs of organization.

Conditions appear to be favorable for this system to become a tropical depression on Friday as it moves west-northwestward near 10 mph. There is a high chance, greater than 50 percent, of this system becoming a tropical cyclone during the next 48 hours.

Winds in the area are estimated to be 20 to 25 knots, and the system is moving west-northwestward at 6 knots. Recent NHC pressure estimates show a decrease in sea level pressure of over 2 mb in the past 24 hours. It is now estimated to be near 1007 mb.

Recent animated multispectral imagery indicates that the low level circulation center (LLCC) has begun to organize with convective banding wrapping into it from all quadrants.

Upper level analysis reveals that the system is in a region of moderate vertical wind shear, but the system has good equatorward outflow and improving poleward outflow due to interaction with an upper level low located north of the system.

The remnants of Blanca, on the other hand, located about 950 miles west of the southern tip of Baja California, are producing a few showers while moving northwestward at 5 to 10 mph.

Blanca Slowing, Expected to Dissipate

Remnant Low of Blanca (03E) - July 9th, 2009

Blanca (03E) has weakened from a tropical depression to a remnant low.  At 8:00 PM PDT (0300 UTC) the center of the system was located about 775 miles (1245 km) west of the southern tip of Baja California.

The low is moving toward the west-northwest near 10 mph and this general motion with a gradual decrease in forward speed is expected until dissipation.

Maximum sustained winds are near 30 mph (45 km/hr) with higher gusts.  Estimated minimum central pressure is 1006 mb (29.71 inches). The low is forecast to slowly weaken over the next couple of days.
