Tropical Report

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Sun Oct 14 2018

For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

1. A broad, low-latitude tropical wave located more than 800 miles east
of French Guiana is producing a large area of cloudiness and
disorganized thunderstorms. Some slight development of this system
is possible during the next day or two before upper-level winds
become unfavorable around mid-week, prior to the disturbance
reaching the northeastern coast of South America. This wave is
expected to move westward at about 15 mph during the next few days.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…10 percent.

For the eastern North Pacific…east of 140 degrees west longitude:

1. A small low pressure system is located about 200 miles south-
southeast of Manzanillo, Mexico. Associated shower and thunderstorm
activity has changed little in organization overnight due to
moderate winds aloft. However, upper-level winds are expected to
gradually become more conducive for development of this disturbance
during the next couple of days, and a tropical depression is likely
to form by early this week while the low moves slowly westward to
west-northwestward just offshore the coast of southwestern Mexico.
Regardless of development, heavy rains are possible along coastal
sections of the Mexican states of Guerrero, Michoacan, and Colima
during the next few days, and interests in those areas should
monitor the progress of this system and refer to products issued by
the Mexican Meteorological Service.
* Formation chance through 48 hours…high…70 percent.
* Formation chance through 5 days…high…80 percent.

2. A low pressure area is forecast to develop a few hundred miles south
of the southeastern coast of Mexico around the middle of next week.
Environmental conditions are expected to be somewhat favorable for
development of the system while it moves generally westward,
parallel to the coast of Mexico.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days…medium…40 percent.

Atlantic satellite image:

The Global Infrared Satellite image shows clouds by their temperature. Red and blue areas indicate cold (high) cloud tops. Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light, but shorter than that of terahertz radiation and microwaves. Weather satellites equipped with scanning radiometers produce thermal or infrared images which can then enable a trained analyst to determine cloud heights and types, to calculate land and surface water temperatures, and to locate ocean surface features.
