As a tropical cyclone approaches or moves over land, intensifies or becomes wider, a wind signal raised over a particular locality can be escalated to a higher wind signal level; multiple wind signals hoisted over various areas can also be escalated, and the extent or area where there are active wind signals can also be expanded.

A Tropical Cyclone Wind Signal (TCWS) is a plain text warning to particular land area that may experience winds of at least strong breeze in strength on the Beaufort Scale (i.e., 39 km/h, 22 kt or higher) within at most 36 hours from the time the signal is put into effect during the passage of a tropical cyclone.

Strong/isolated severe storms will be possible from eastern Texas eastward across the Lower Mississippi Valley. For additional details, see the latest Day 1 Convective Outlook.
