What: A marginal risk of severe weather and excessive rainfall is anticipated.

When: The risk will be present from late morning through the evening hours.

Where: The affected areas include all of southeastern Louisiana and southern Mississippi.

Confidence: Meteorologists have a high level of confidence in the occurrence of pop-up thunderstorms throughout the area today. While most storms are expected to be localized and minor, some may be locally strong and result in minor flooding.

Impacts: The potential effects of this weather system include:

• Locally strong wind gusts: Wind gusts ranging from 40 to 50 mph are expected. In isolated cases, severe storms may produce up to 60 mph gusts, posing a risk of tree and powerline damage.
• Excessive rainfall: Rainfall rates of 2 to 4 inches (or more) per hour are anticipated, which could result in ponding across low-lying areas. Flash flooding is also possible due to the heavy downpours.
• Underpass drainage: Given the forecasted hourly rainfall rates, underpasses may need help to drain effectively.

The parish advises residents in the affected areas to stay alert and monitor local weather updates. Individuals should take necessary precautions to ensure their safety, such as securing loose outdoor items and avoiding low-lying areas prone to flooding.
