PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NEW ORLEANS LA

..PUBLIC INFORMATION STATEMENT
DURING THE EARLY MORNING HOURS OF SATURDAY APRIL 10, A SEVERE
THUNDERSTORM PRODUCED SIGNIFICANT WIND DAMAGE ALONG A SWATH FROM
THE CAPITAL HEIGHTS REGION OF BATON ROUGE SOUTHEASTWARD ROUGHLY
ALONG AIRLINE HWY/HWY 61 THROUGH THE ST. AMANT AND ACY AREAS - A
SWATH OF APPROXIMATELY 25 MILES.
THE STRONGEST WINDS APPEAR TO HAVE OCCURRED IN THE VICINITY OF
THE EAST BATON ROUGE/ASCENSION PARISH LINE WHERE 3 HIGH POWER
TRANSMISSION TOWERS WERE TOPPLED. IN THIS AREA, WIND GUSTS WERE
LIKELY 80 MPH OR HIGHER. OTHER DAMAGE ALONG THE SWATH INCLUDES
NUMEROUS TREES AND LARGE LIMBS DOWN, AND A FEW POWER POLES
SNAPPED. STRUCTURAL DAMAGE OUTSIDE OF TREES FALLING ON HOMES
WAS MAINLY LIMITED TO ROOFS AND CARPORTS.
BASED ON RADAR DATA AND THE PICTURES WE HAVE RECEIVED THUS FAR,
ALONG WITH CONVERSATIONS BETWEEN OUR METEOROLOGISTS AND THE
LOCAL EMERGENCY MANAGEMENT AGENCIES, WE CURRENTLY BELIEVE THIS
DAMAGE WAS DUE TO STRAIGHT LINE WINDS FROM A SOMEWHAT LONG-LIVED
DOWNBURST.
NO FORMAL SURVEY OF THE DAMAGE IS CURRENTLY PLANNED. HOWEVER, WE
CONTINUE TO EXAMINE THE EVIDENCE AND IF IT IS DETERMINED A SURVEY
IS NEEDED, WE WILL CONDUCT ONE.
