[image-78]Wind Shear Wipes Out Tropical Cyclone Elida

Strong northwesterly wind shear took its toll on Tropical Storm Elida, weakening it to a remnant low early on July 2. In infrared satellite imagery from NOAA's GOES-West satellite, Elida appeared to be a tight swirl of low clouds devoid of any deep convection. 

Infrared satellite instruments are used to see the heat objects emit. During night-time hours when there's no sunlight to light clouds, satellites like NOAA's Geostationary Operational Environmental Satellite or GOES-West satellite looks at clouds in infrared light. Infrared data from NOAA's GOES-West satellite on July 2 at 9:00 UTC (5 a.m. EDT) was made into an image at NASA/NOAA's GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md. The image showed Elida was almost devoid of convection (rising air that creates powerful thunderstorms that make up a tropical cyclone).

The National Hurricane Center or NHC issued their final bulletin on Elida on Wednesday, July 2 at 5 a.m. EDT (9:00 UTC). Maximum sustained winds were near 30 mph (45 kph) and weakening.  The center of Post-Tropical Cyclone Elide was located near latitude 16.9 north and longitude 103.0 west, about 170 miles (270 km) south-southeast of Manzanillo Mexico The post-tropical cyclone is moving toward the southeast near 3 mph (6 kph).

The NHC expects the remnants to move westward by Thursday due to a building low-level ridge (elongated area of high pressure) over the eastern Pacific. By July fourth, Eilda's remnants are expected to degenerate into a trough or elongated area of low pressure.

[image-51]July 01, 2014 - NASA's Aqua Satellite Sees Tropical Storm Elida Close to Southwestern Mexico Coastline

NASA's Aqua satellite passed over Tropical Storm Elida on July 1 and captured infrared data on the storm. The satellite image showed that Elida was close to southwestern Mexico, and Tropical Storm Warnings are in effect.

An infrared image of Elida was obtained by the Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite. The AIRS data was captured on July 1 at 08:47 UTC and showed powerful thunderstorms around Elida's center very close to the coast of southwestern Mexico. 

A Tropical Storm Warning is in effect from Lazaro Cardenas to Cabo Corrientes.

At 8 a.m. EDT (1200 UTC) the center of Tropical Storm Elida was stationary near latitude 17.4 north and longitude 104.3 west, about 110 miles (180 km south of Manzanillo, Mexico. Elida is expected to move south and southeast later on July 1 and 2 before turning to the west, according to the National Hurricane Center (NHC). Maximum sustained winds remain near 50 mph (85 kph) and some weakening is forecast during the next 48 hours. The estimated minimum central pressure is 1003 millibars.

Elida is close enough to the coast to cause ocean swells and rip tides, heavy rainfall and tropical storm-force winds. NHC noted that Elida is expected to produce total rain accumulations of 1 to 3 inches over the western portions of the Mexican states of Colima and Michoacan and over the southwestern portion of Jalisco. Isolated maximum amounts of 5 inches are possible in these areas.
