eastern pacific Hurricane Marty

[Somerset Squall]

A new tropical depression has formed southwest of Acapulco, Mexico. The depression has winds of 30kts, and is characterised by a well defined LLC with formative banding features but only shallow convection over the LLCC. 17E is heading slowly northwards towards the coast of Mexico. Models are in disagreement as to whether the northward motion will last long enough for 17E to move inland or stop just short of the coast. Regardless, heavy rains are set to affect southern Mexico has 17E nears the coast. Moderate shear will prevent rapid intensification, but 17E is still expected to become a strong tropical storm before being killed by land or even stronger shear, which is set to arrive in about 72hrs.

The depression has organised quickly, and is now a 50kt tropical storm named Marty. Marty has a central dense overcast with very cold cloud tops, and also strong convective banding features. Marty is now expected to become a hurricane as it continues to approach the coast.

Marty has become a hurricane with winds of 70kts. The hurricane continues to crawl towards the coast. Heavy rains and strong winds will spread inland, even if the core of Marty remains offshore. Marty has probably peaked as shear and land interaction should serve to weaken the hurricane from now.

Marty did not make landfall and turned westwards before reaching the coast. The system has now shorn apart as it moves away from the coast. Regeneration is not expected.
