The potential for significant flash flooding will be highest this evening through Thursday morning, especially where heavy rain/intense rainfall rates repeatedly moves over the same locations.

Significant rises in several rivers are ongoing - visit https://water.noaa.gov/ for the latest forecast.

Additional rainfall tonight will worsen/prolong river flooding.A few strong/severe storms will be capable of damaging winds up to 60 mph and a few tornadoes.

Minor coastal flooding and hazardous marine conditions will become increasing concerns Wednesday and Thursday with 2 to 4 feet of inundation above normally dry ground in SW LA, 1-3 ft in SE LA.

Weather Update - Wednesday, 6/17 @ 7am

Here is an update concerning the heavy rain and tropical threat this week.

Changes from previous update:

The greatest area of threat for heavy rainfall/flash flooding has narrowed slightly. (The threat itself has not changed significantly.)

The threat of Potential Tropical Storm One becoming a tropical storm has decreased slightly.

Overview:

WHAT: SLIGHT RISK to MODERATE RISK of Heavy Rain that could lead to flash flooding

WHEN: starting this afternoon through Friday

WHERE: most of southeast Louisiana and southeast Missisippi, especially near the I-10/I-12 corridor

CONFIDENCE:

We are confident in a lull in showers and storms today and that the amount will increase starting tonight into tomorrow, bringing significant flash flooding in localized areas.

We have less confidence in where exactly the heaviest rain will fall.Confidence is lower that Potential Tropical Cyclone One becomes a tropical storm this afternoon.

However, confidence is high that there will be multi-hazard impacts regardless of development.

Impacts:

Widespread areas of 3-6 inches of rain with locally higher amounts in excess of 10 inches.

Minor coastal flooding of up to 1 to 3 feet above normally dry ground mainly for south-facing shores of coastal LA .

Stronger storms today through Friday will be capable of producing brief tornadoes and 30-50 mph winds.

As water drains into area rivers, there will be a threat of minor to moderate with potential for major flooding along some rivers.

The graphics below highlights the threats associated with this system.

🌀Tropical Weather Update - 6/16 - 10am

Here is an update concerning the potential for tropical cyclone development near the TX Coast through Wednesday night and associated impacts to the local area today through Friday.

What is a PTC? Potential tropical cyclone advisories allow the National Hurricane Center to issue watches and warnings for disturbances that are not yet meeting tropical cyclone criteria, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 72 hours.

Changes from previous update:

Advisories have been initiated by the National Hurricane Center on Potential Tropical Cyclone One.

The chance of this system bringing impacts to the local areas has increased.

The axis of heaviest rainfall has shifted southeast toward the I-10/12 corridor from central LA and SW MS.

The threat of excessive rainfall leading to flash flooding across the local area associated with this system has increased.

Overview:

There is a MEDIUM (60%) chance of tropical cyclone development over the next 2 days.

This system is forecast to move generally northeastward and will bring impacts to the southeast Louisiana and southern Mississippi Wednesday through Friday.

Confidence:

Confidence is medium that this system will become a tropical cyclone before moving inland over Texas on Wednesday night.

Confidence is medium that this system will track inland over central Louisiana and central MS Wednesday through Friday.

While there is uncertainty regarding the eventual track and timing of this system and whether it will develop, we are confident it will still bring a threat of excessive rainfall leading to flash flooding, minor coastal flooding, and unsettled marine weather to the local area.

If the track were to shift further east, the axis of heaviest rainfall would be centered across the I-10/12 corridor potentially including the New Orleans and Baton Rouge metros.

Impacts:

Specific impacts will depend on the exact track and timing of this system as it passes the area. However, there is a medium to high chance it will bring a multi-hazard threat to the local area Wednesday through Friday.

Widespread areas of 3-6 inches of rain with locally higher amounts upwards of 8-10 inches.

IF the track were to shift further east, localized totals could reach upwards of 15" leading to significant flash flooding, especially in urban and poor drainage areas.

Minor coastal flooding of up to 1 to 3 feet above normally dry ground mainly for south-facing shores of coastal LA and.

Stronger storms today through Friday will be capable of producing brief tornadoes and 30-50 mph winds.

Overview:

WHAT: SLIGHT RISK to MODERATE RISK of Heavy Rain that could lead to flash flooding

WHEN: Multiple rounds of heavy rainfall will occur each day this week, but the heaviest rainfall is projected to occur on Thursday as a low pressure system moves through the state.

WHERE: All of Southeast Louisiana and Southern Mississippi.

CONFIDENCE: We are confident there will be multiple rounds of thunderstorms that will produce heavy rainfall in the area each day this week, but we have less confidence in exactly where these thunderstorms will develop and where the heaviest rainfall will occur each day.

Impacts:

Rainfall of 4 to 6 inches is currently forecast through Friday.

There is a medium chance of local amounts reaching 10 inches or more. There is a high chance that high rainfall rates of 2 to 5 inches per hour will result in several areas of flash flooding.

As water drains into area rivers, there will be a threat of flooding along some rivers

Plaquemines Parish Special Medical Needs Residents are Eligible for Assistance with Evacuation

Are you a Plaquemines Parish resident with Special Medical Needs that requires evacuation assistance during Hurricane Season?

In preparation for the 2026 Hurricane Season, we urge all individuals who have been diagnosed with conditions needing special medical attention, such as insulin therapy, oxygen therapy, dialysis, cardiac drugs/treatment, etc., to make plans and arrangements WELL IN ADVANCE with your private physician, your clinic, and your family for treatment during a hurricane evacuation. Regular shelters, such as the one at Multipurpose Center, are not equipped to handle evacuees requiring special medical attention. All Special Medical Needs patients will require a caretaker to evacuate with the patient.

Any Plaquemines Parish resident who is now totally bed bound and will require assistance during an evacuation is urged to contact us NOW to pre-register.

The Plaquemines Parish Special Medical Needs Program will now be working with the State of Louisiana for sheltering of patients meeting important criteria. The Department of Health and Hospitals has identified select facilities in Louisiana, where medical care will be given to Special Medical Needs patients.

Some of the advantages of participating with the state plan include:
• The facility will be located outside of the danger zone of the hurricane
• Medical care will be provided for all special medical needs patients during the entire duration of the storm event
• Transport by ambulance will be provided from Belle Chasse to a facility determined by DHH-OPH

Responses and/or questions, regarding this announcement are to be directed to the Plaquemines Parish Health Department at 504-934-6690.
