Tropical Storm Kevin developed several hundred miles southwest of Mexico and is expected to strengthen slowly as it moves northward through Thursday.

The storm formed as Tropical Depression 14-E on Monday before reaching tropical storm strength.

While warm waters and tolerable wind shear will promote some strengthening, ultimately cooler waters and higher wind shear await the tropical system as it continues to the north during the second half of the week.

These factors will result in a weakening storm system as it begins to approach southern Baja California from Friday into this weekend.


The strong southwest wind shear will lift tropical moisture northeastward into Baja California and northern Mexico as early as Thursday with enhanced rain and thunderstorms expected to continue through the weekend.

In fact, some of this moisture will likely reach Arizona and New Mexico, resulting numerous showers and thunderstorms from Friday through the weekend.

While the combination of cooler waters and strong wind shear will likely result in weakening into a post-tropical low pressure over the open Pacific Ocean this weekend with no landfall expected, moisture from the storm can still cause localized flash flooding across Baja California and northern Mexico.
