DISCUSSION AND OUTLOOK
At 800 PM EDT (0000 UTC), the center of Tropical Storm Danny was located near latitude 32.3 North, longitude 80.5 West. Danny is moving toward the west-northwest near 16 mph (26 km/h) and this general motion is expected to continue during the next day or so. On the forecast track, Danny will move inland across southern South Carolina and east-central Georgia tonight and early Tuesday morning.

Data from NOAA Doppler radars, earlier reconnaissance aircraft, and surface observations indicate that maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Rapid weakening is forecast, and Danny is expected to weaken to a tropical depression later tonight and dissipate by late Tuesday.

Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center. A wind gust of 34 mph (55 k/h) was recently reported at Beaufort Airport in South Carolina. The minimum central pressure based on surface observations is estimated to be 1010 mb (29.82 inches).

HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected to continue in the warning area during the next few hours.

RAINFALL: Danny could produce 1 to 3 inches of rainfall with locally higher amounts along the immediate coasts of Georgia and southern South Carolina. This region has been dry, limiting potential widespread flooding impacts, however, local flooding impacts, especially in urban areas along the southern South Carolina and Georgia coasts, cannot be ruled out at this time. Farther inland, 1 to 2 inches of rainfall is possible across Upstate South Carolina, the Piedmont of Georgia, and into northeastern Alabama.

STORM SURGE: The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide…

* Port Royal Sound, SC to South Santee River, SC…1 to 3 ft

Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.

TORNADOES: An isolated tornado will be possible this evening along the South Carolina coast.
