As Tropical Storm Ernesto continues to move westward, the weather will continue to be very stormy in central Mexico through today.
The storm made landfall around 11 PM EDT Tuesday along the southern coast of the Yucatan Peninsula as a category 1 hurricane with 85 mph. By early Wednesday morning, Ernesto was downgraded to a tropical storm but was pelting the Yucatan with 70 mph winds and torrential rainfall.
Ernesto has gathered a large field of moisture in the form of towering showers and thunderstorms, capable of unleashing a foot of rain in parts of central Mexico through the end of the week.
Rainfall rates of up to a couple of inches per hour can not only overwhelm streams and drainage systems, but lead to mudslides in hilly and mountainous areas inland of the coast.
Strong wind gusts, generally in the vicinity of severe thunderstorms wrapping around the large circulation of the storm also bring the risk of damaging wind gusts at a more local level. The severe thunderstorms can occur hundreds of miles away from the center of Ernesto.
The outer bands of the storm pounded Honduras on Monday with heavy rain and gusty winds.
A large dome of high pressure north of the storm should keep Ernesto on a westerly track toward Mexico and away from the U.S. A second landfall is likely near the city of Veracruz on Friday.

As far as the United States is concerned, Ernesto is expected to have little or no impact aside from some rough surf along the Texas coast.
Elsewhere in the Atlantic, there are no other active tropical systems. A few tropical waves are being monitored, but none show signs of immediate development.

New York/MA (1819)
Two simultaneous cloudbursts, 45 miles apart; A bucket survey claimed 15" of rain fell at Catskill, NY. Highways were completely washed out. One washout started west of the old Albany Post Road and spread eastward across the road until it was 190 feet wide and 80 feet deep in a distance of 160 paces. At Westfield Valley, "suddenly the windows of heaven seemed to have been opened and the rain fell in such torrents that in less than 5 hours, Westfield River rose at least 20 feet above its usual height at low water. The river overflowed its banks with great rapidity and violence, sweeping away every bridge, fence and building which opposed its current."
