Tropical Storm Cristobal Causes Storm Surge on Gulf Coast

Tropical Storm Cristobal caused a storm surge on the Gulf Coast on Sunday.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Cristobal was located at latitude 30.3°N and longitude 90.2°W which put it about 20 miles (30 km) north-northwest of New Orleans, Louisiana.  Cristobal was moving toward the north-northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 993 mb.

A Tropical Storm Warning remained in effect for the portion of the coast from Morgan City, Louisiana to the Okaloosa/Walton County Line in Florida.

The large circulation around Tropical Storm Cristobal blew water toward the northern coast of the Gulf of Mexico on Sunday.  The wind produced a rise in the water level from northwest Florida to southeast Louisiana.  The highest storm surges occurred along the coast of Mississippi and southeast Louisiana.  The water level reached 7.47 feet (2.28 m) at the Waveland Yacht Club in Mississippi.  The storm surge was 7.62 feet (2.32 m) at Shell Beach in Louisiana.  The storm surge covered coastal roads in Grand Isle, Louisiana and Biloxi, Mississippi.

The broad center of Tropical Storm Cristobal passed across the Lower Mississippi River delta on Sunday afternoon before it moved over New Orleans.  Cristobal began to weaken slowly as it moved inland.  Winds to tropical storm force were still occurring in the southeastern part of the circulation which was still over the Gulf of Mexico.  Most of the rain was falling in bands on the northern side of Tropical Storm Cristobal.  Locally heavy rain fell over Northwest Florida, Southwest Alabama, Southern Mississippi and Southeastern Louisiana.

Tropical Storm Cristobal will move around the western end of a subtropical high pressure system over the western Atlantic Ocean.  The high will steer Cristobal toward the north during the next several days.  On its anticipated track Tropical Storm Cristobal will move over Louisiana and Arkansas on Monday.  Cristobal will continue to weaken slowly as it moves farther inland.  Tropical Storm Cristobal will drop locally heavy rain over parts of Mississippi, eastern Louisiana, Arkansas and Missouri.  Flood Watches have been issued for some of those areas.
