Tropical Depression 19-E has dissipated over the mountainous terrain of northwestern Mexico. Despite this, heavy rainfall and flash flooding will continue on Thursday across Sonora.

We are also monitoring an area of low pressure around 1,000 miles southwest of the southern tip of Baja California. This system may develop over the next day or two as it tracks west-northwestward over the open waters of the East Pacific.

Finally, we anticipate that an area of low pressure will develop in a few days well to the south of the southern Mexican coast. This low would move parallel to the southwestern coast of Mexico and may have a chance to further develop and organize by early next week.

Elsewhere in the East Pacific basin, development is not anticipated through at least this weekend.

For Friday morning we’ll see some small, South swell action come into play with waist to possibly chest high sets from a fairly liberal angle of 210-215 degrees with 16 second intervals. Not a large swell, but with the long intervals it should have a little oomph to it.

ABOUT THE SWELLMAGNET FORECAST – One of the most exciting–and yet most challenging–aspects of surfing is the sheer variety of waves and weather conditions that affect the entire surfing experience.

This is important for ensuring both a safe and enjoyable experience.
