Carlotta made landfall near Puerto Escondido, Mexico, late Friday night while unleashing torrential rains in mountainous areas.
The AccuWeather.com Hurricane Center has the latest statistics on Carlotta.
At the time of landfall, wind gusts were estimated to be around 90 mph near the storm's center.
The interaction with land, in particular the Sierra Madre del Sur, has caused Carlotta to rapidly weaken over the past 24 hours. The storm is now a tropical rainstorm.
Carlotta will encounter weakening steering currents over the next few days, which will allow the storm to remain inland over southern Mexico through early next week.
This is terrible news for residents and vacationers to southern Mexico as several days of heavy rains are in the forecast, which will lead to mudslides and potentially life-threatening flooding.
Two children were killed early Saturday morning in the town of Pluma Hidalgo, Oaxaca when their home collapsed in a landslide caused by heavy rains.
Local rainfall totals through early next week will average 4 to 8 inches over portions of southern Mexico from western Oaxaca through much of the state of Guerrero.
Greater than a foot of rain are possible for the mountains of Oaxaca and Guerrero, as upslope flow enhances rainfall. At least a portion of the storm will linger across the region, allowing a deluge to last for days.
Landslides and mudslides could occur in higher elevations along with significant flooding.
In addition, southerly winds on the backside of Carlotta will lead to significant coastal flooding from from Punta Maldonado to Acapulco.
