ELIDA A LITTLE STRONGER AS IT MOVES OVER THE OPEN EAST PACIFIC
According to the NHC Advisory number 4
Elida is moving toward the west near 15 mph (24 km/h), and this general motion is expected to continue today followed by a gradual turn to the west-northwest and northwest over the next few days. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Gradual strengthening is forecast over the next day or so followed by a somewhat faster rate of intensification. Elida is forecast to become a hurricane on Friday. Tropical-storm-force winds extend outward up to 90 miles (150 km) from the center.
>>> Offshore of Southern and Southwestern Mexico:
An area of low pressure is expected to form later this week several hundred miles south of the coast of southern Mexico.
Environmental conditions appear conducive for gradual development of this system thereafter, and a tropical depression is likely to form by this weekend into early next week while it moves generally west-northwestward well offshore of Mexico.
* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…high…80 percent
