...April 23rd through 25th...
A closed area of low pressure and associated surface low pressure
area moved slowly from the lower Mississippi Valley northeast
across the Tennessee Valley and into the Carolinas and Virginia
over the 3-day period. This produced locally heavy rainfall
across the Carolinas and Georgia. The rainfall produced high flows
on the area rivers. Minor to moderate river flooding occurred
along the Congaree River at Carolina Eastman, Congaree River at
the Congaree National Park-Gadsden and the Great Pee Dee River at
Cheraw. The river flooding produced flooding of significant
portions of the Congaree National Park. This includes some of the
hiking trails and elevated boardwalks. Cedar Creek within the park
rose nearly 7 feet as water filled the park. The creek crested at
10.24 feet on the 27th.

Here are the highest crests of each river:

The Congaree River at Carolina Eastman (CEAS1)...119.70 feet on
the 26th. Flood Stage is 115.0 feet.

The Congaree River at the Congaree National Park-Gadsden
(GADS1)...17.20 feet on the 26th. Flood Stage is 15.0 feet.

The Great Pee Dee River at Cheraw (CHES1)...31.20 feet on the
26th. Flood Stage is 30.0 feet.

The Water River at Lake Wateree (WATS1)...99.49 feet on the 26th.
Flood Stage is 100.00 feet.


...April 30th...
Chilly Canadian high pressure settled southward into the Carolinas
and Georgia during late April. High pressure settled over the area
on the morning of the 30th. This produced good radiational cooling
conditions and chilly temperatures for late April.

Here are some of the morning low temperatures on the 30th:

The 3-Month Outlook for Spring/Summer
(May/June/July)...

The outlook calls for a 40 to 50 percent chance of above normal
temperatures along with equal chances of above, below or normal
precipitation.

Go to the Climate Prediction Center web page at
www.cpc.ncep.noaa.gov for more details and the latest outlooks.

ENSO (EL NINO SOUTHERN OSCILLATION)...
...La Nina Advisory...

Equatorial sea surface temperatures are near-to-below average
across the central and eastern Pacific Ocean. La Nina is expected
to transition to ENSO-neutral during May, with ENSO-neutral then
likely to continue through the Northern Hemisphere Summer 2018.
There is a greater than 50 percent chance of ENSO-neutral
conditions through the Summer.
