500 AM PDT Thu May 20 2021
For the eastern North Pacific...east of 140 degrees west longitude:
1. A low pressure system could still form during the next day or so a
few hundred miles south of the Gulf of Tehuantepec. However, shower
and thunderstorm activity has decreased in coverage over this
system, and additional development is looking less likely as
environmental conditions are forecast to become less conductive for
tropical cyclone formation by this weekend.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
