From the Lake Charles NWS Forecast Discussion:

...BUOY DATA IN THE GULF INDICATES THE 34KT WIND RADII IS VERY LARGE
WITH IKE AND EXTENDS OUTWARD UP TO 255 MILES TO THE NORTHEAST OF
THE EYE. THIS GREAT EXPANSE OF TROPICAL STORM FORCE WINDS
HAS PROMPTED THE ISSUANCE OF TROPICAL STORM WIND WATCHES FOR ALL
OF SOUTHEAST TEXAS AND MUCH OF CENTRAL AND SOUTHERN LOUISIANA.
WATCHES WILL LIKELY BE UPGRADED TO WARNINGS LATER TODAY. HIGHLY
CONCERNED ABOUT POTENTIAL STORM SURGE AS IKE'S LARGE WIND FIELD
AND LENGTHY TIME OF ONSHORE FLOW COMBINE ALONG OUR COAST.
