    Monitoring several features in the East and Central Pacific basins

    7/19/2018 4:44:17 PM

    We are watching several areas for potential development across the East Pacific basin at this time.

    The first is a tropical wave around 1,400 miles to the southwest of the southern tip of Baja California. Satellite imagery shows a disorganized area of showers and thunderstorms associated with this tropical wave as it continues to track westward. This feature will remain well away from any land masses over the next several days.

    The second area is low pressure that will likely develop well southwest of Mexico this weekend. The low will form in a zone of low shear and warm ocean waters, so further development and organization of this feature are possible by the end of the weekend or early next week.

    Another low pressure area should develop this weekend off the coast of Central America located to the west of El Salvador and Nicaragua. This feature may develop early next week as it moves west-northwestward away from the coast of Central America.

    In the Central Pacific basin, we are also monitoring a feature for potential development. Satellite imagery shows an area of showers and thunderstorms associated with a broad area of low pressure currently located around 950 miles to the southeast of Hilo, Hawaii. Further development and organization of this low is possible over the next few days as it tracks off to the west.

    A broad area of low pressure located about 1400 miles southwest of
    the southern tip of the Baja California peninsula continues to
    produce a large area of disorganized showers and thunderstorms.
    Environmental conditions appear conducive for gradual development of
    this system while it moves quickly westward during the next few
    * Formation chance through 48 hours...low...30 percent.
    * Formation chance through 5 days...medium...50 percent.
    An area of showers and thunderstorms located several hundred miles
    southwest of Mexico is associated with a westward-moving tropical
    wave.  A low pressure area is expected to form this weekend from
    this wave and gradual development is possible early next week while
    it continues westward.
    * Formation chance through 48 hours...low...10 percent.
    * Formation chance through 5 days...medium...40 percent.
    Another area of low pressure is likely to form early next week
    several hundred miles south of the southern coast of Mexico.
    Conditions appear conducive for some development of this system
    thereafter while it moves west-northwestward.
    * Formation chance through 48 hours...low...near 0 percent.
