Hurricane Blanca Monday

Blanca Makes Record Landfall on Baja California Peninsula

Despite weakening, Blanca continues to set hurricane records and unleash flooding rain on Mexico’s Baja California peninsula.

Blanca set its second tropical record in the eastern Pacific Basin on Monday. As a tropical storm, Blanca made landfall near Puerto Cortes, Mexico, early Monday morning. That marks the earliest landfall of a tropical cyclone on the Baja California peninsula.

The previous earliest landfall on the Baja California peninsula was Calvin from 1993, according to the National Hurricane Center. Reliable records have been kept for the eastern Pacific Basin since 1971.

Blanca first entered history books when it strengthened into a major hurricane last week, becoming the earliest second major hurricane in the eastern Pacific. There have only been four other seasons that have had two major hurricanes develop before the end of June.

Blanca is no longer a major hurricane, as it was forced to weaken as it tracked over the significant cooler waters south of the Baja California peninsula. Combined with interaction with land, Blanca is expected to weaken to a tropical depression by Monday night.

Blanca, however, will continue to threaten the central Baja California peninsula with flooding rain through Monday night. The rain will generally total 75 to 150 mm (3 to 6 inches). The heaviest rain will pour down across the northern half of Baja California Sur and neighboring parts of Baja California Norte.

The threat of locally damaging winds will gradually diminish as Blanca weakens.

By Tuesday, moisture from the dissipating system will move across Baja California Norte and northwestern Sonora bringing the threat for isolated flash flooding. Wind will no longer be a threat.

According to AccuWeather Senior Meteorologist Alex Sosnowski, “The remnants of Blanca will inject another dose of moisture, in the form of showers and thunderstorms into the southwestern U.S.this week.”

Along with beneficial rain in some areas, too much rain could fall too fast to cause isolated incidents of flooding.

The moisture will follow only a few days behind some moisture produced by the remnants of Andres.
