An area of disturbed weather with an associated surface low formed over the Yucatan Peninsula of Mexico in mid-June. The system
was a broad monsoon depression/Central American Gyre-type low with a broad wind and cloud/rain shield. It drifted to the west-
northwest, emerging into the Bay of Campeche. Moving northwest, and then west, the system became well enough defined to be
considered a tropical storm on June 19th. Slow to develop due to its large size, Alberto sloshed ashore east-central Mexico
on the morning of the 20th near Tampico, then accelerated west across the country, devolving into a disturbed weather area
as it moved offshore southwest Mexico and south of Baja California by the morning of the 21st.
The graphics below show the storm total rainfall for Alberto, which used rain gage information from National Weather Service River Forecast
Centers, xMACIS2, National Weather Service Forecast Offices, and CoCoRAHS.
