SITUATION OVERVIEW ------------------

Tropical Storm Bertha is currently south of the coast of the Florida Panhandle and will gradually continue to move northwest. Some slight additional strengthening is possible on Tuesday prior to it turning more westward toward southeast Louisiana on Wednesday. Bertha is forecast to bring the threat of tropical storm force wind gusts and locally heavy rainfall generally south of I-10, and coastal flooding of up to 2 to 4 feet above normally dry ground. The coastal areas of Mississippi and southeast Louisiana will have the greatest threat, especially along and south of I-10.

Coastal Flood Warnings are now in effect for coastal Mississippi and Southeast St. Tammany to the Mouth of the Mississippi River. Coastal Flood Advisories are now in effect for north and west shores of Lake Pontchartrain and the Jefferson/Lafourche Parish Line to Morgan City, Louisiana.

Tropical Storm Warnings are in effect from the Bay/Gulf County Line in Florida border west to the Lafourche/Terrebonne Parish Line in southeast Louisiana. Tropical Storm Watches are in effect from the Lafourche/Terrebonne Parish Line to the Vermilion/Cameron Parish Line, Louisiana. Additionally, Tropical Storm Watches remain in effect for the City of New Orleans including Lakes Pontchartrain and Maurepas, inland portions of coastal Louisiana Parishes as well as inland coastal Mississippi Counties of Jackson, Harrison, and Hancock.

POTENTIAL IMPACTS -----------------

* WIND: Protect against hazardous wind having possible limited impacts across portions of southeast Louisiana and coastal Mississippi. Potential impacts in this area include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages.

Elsewhere across Southeast Louisiana and South Mississippi, little to no impact is anticipated.

* SURGE: Protect against coastal flooding having possible significant impacts across coastal southeast Louisiana and Mississippi. Potential impacts in this area include: - Areas of inundation with storm surge flooding accentuated by waves. Damage to several buildings, mainly near the coast. - Sections of near-shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. - Major beach erosion with heavy surf breaching dunes. Strong and numerous rip currents. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages.

Elsewhere across Southeast Louisiana and South Mississippi, no impact is anticipated.

* FLOODING RAIN: Protect against locally hazardous rainfall flooding having possible limited impacts across Southeast Louisiana and South Mississippi. Potential impacts include: - Localized rainfall flooding may prompt a few evacuations. - Rivers and tributaries may quickly rise with swifter currents. Small streams, creeks, canals, and ditches may become swollen and overflow in spots. - Flood waters can enter a few structures, especially in usually vulnerable spots. A few places where rapid ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Several storm drains and retention ponds become near-full and begin to overflow. Some brief road and bridge closures.

* TORNADOES: Little to no impacts are anticipated at this time across Southeast Louisiana and South Mississippi.

PRECAUTIONARY/PREPAREDNESS ACTIONS ----------------------------------

* EVACUATIONS: Follow the advice of local officials.

* OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding.

If you are relocating to safe shelter, leave as early as possible. Allow extra time to reach your destination. Many roads and bridges will be closed once strong winds arrive. Check the latest weather forecast before departing and drive with caution.

Keep cell phones well charged. Cell phone chargers for automobiles can be helpful, but be aware of your risk for deadly carbon monoxide poisoning if your car is left idling in a garage or other poorly ventilated area.

It is important to remain calm, informed, and focused during an emergency. Be patient and helpful with those you encounter.

If you are a visitor, be sure to know the name of the city or town in which you are staying and the name of the county or parish in which it resides. Listen for these locations in local news updates. Pay attention for instructions from local authorities.

Storm surge is the leading killer associated with tropical storms and hurricanes! Make sure you are in a safe area away from the surge zone. Even if you are not in a surge-prone area, you could find yourself cutoff by flood waters during and after the storm. Heed evacuation orders issued by the local authorities.

Closely monitor weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings.

PRECAUTIONARY/PREPAREDNESS ACTIONS ----------------------------------

* EVACUATIONS: Follow the advice of local officials.

OTHER PREPAREDNESS INFORMATION: Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business.

When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm.

If in a place that is vulnerable to high wind, such as near large trees, a manufactured home, upper floors of a high-rise building, or on a boat, plan to move to safe shelter.

If you live in a place particularly vulnerable to flooding, such as near the ocean or a large inland lake, in a low-lying or poor drainage area, in a valley, or near an already swollen river, plan to move to safe shelter on higher ground.

Always heed the advice of local officials and comply with orders that are issued. Do not needlessly jeopardize your life or the lives of others.

When securing your property, outside preparations should be concluded as soon as possible before conditions deteriorate. The onset of strong gusty winds or flooding can cause certain preparedness activities to become unsafe.

Be sure to let friends and family members know of your intentions for weathering the storm and your whereabouts. Have someone located away from the threatened area serve as your point of contact. Share vital contact information with others. Keep cell phones handy and charged.

Check on those who may not be fully aware of the situation or who are unable to make personal preparations.

If you are a visitor, know the name of the county or parish in which you are located and where it is relative to current watches and warnings. If staying at a hotel, ask the management staff about their onsite disaster plan. Listen for evacuation orders, especially pertaining to area visitors.

Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast.

There is a threat from tornadoes with this storm. Have multiple ways to receive Tornado Warnings. Be ready to shelter quickly.
