We continue to monitor a disorganized disturbance currently over Southeast Louisiana. Based on the current structure of the disturbance (storms displaced well away from the center), the chances of it developing into a tropical depression later today are decreasing. The National Hurricane Center is now giving this system a 10% chance of development into a tropical depression, which is a lower probability than previous outlooks. Regardless of development, a surge of tropical moisture could enhance the risk of heavy showers and thunderstorms in Southeast Texas on Friday.
Key Messages A surge of tropical moisture may bring showers and thunderstorms to SE Texas late this week. Slight Risk (level 2 of 4) of Excessive Rainfall for areas east of I-45 on Friday. Marginal Risk (level 1 of 4) of Excessive Rainfall for areas east of College Station through Saturday. What We’re Watching This heavy rainfall threat will greatly depend on how a disturbance over Florida evolves over the next several days. Actions Remain weather-aware and stay tuned for forecast updates!
