LOUISIANA WEATHER - June 30, 2010

SOUTHWEST LOUISIANA: There is a 90 percent chance for thunderstorms today with an 80 percent chance for tonight. Tomorrow has a 70 percent chance daytime and 50 percent chance nighttime thunderstorms. Friday calls for a 50 percent daytime and 30 percent nighttime chance for thunderstorms. Saturday has a 40 percent daytime and 30 percent nighttime thunderstorm probability. For Sunday (Independence Day) there is a 40 percent daytime and 20 percent nighttime for thunderstorms
Temperatures: Today: 85/74, Thursday: 88/73, Friday: 92/75, Saturday: 90/75, Sunday: 90/74
HAZARDOUS WEATHER: Outer rain bands associated with Hurricane Alex will sweep westward through the western upper Gulf coast states. Widespread rain with embedded heavy showers and thunderstorms can be expected. A flash flood watch is in effect for the coastal marshes and I-10 prairies. Long-period southerly swells associated with Hurricane Alex are generating a minor breaker run up at the coast resulting in an abnormal rise in water levels over and above the predicted astronomical tides. The actual tide levels this morning will be running from 3 to 3.5 feet above mean lower low water. The widespread rains will give way to more scattered showers and thunderstorms as the remains of Alex merge with a mid-west cold front which stalls across the Louisiana coastal waters.


The Atchafalaya River at Morgan City is currently at 4.32 feet (minor flood stage). Minor flood stage is from 4 to 7 feet. The river is expected to fluctuate between to 4.32 feet and 4.5 feet through Sunday. At 4 feet, water will move up the bank and across access roads below the city dock. Floodwall gates should be closed by the 5 foot stage to protect against higher stages. Vessel traffic will be affected by stronger river current and vessel traffic safety rules will be strictly enforced by the U. S. Coast Guard.

SOUTHEAST LOUISIANA: There is a 90 percent chance for thunderstorms today decreasing to 70 percent tonight. Tomorrow the chance for thunderstorms is 70 percent day and 40 percent night. Friday and Saturday calls for a 40 percent chance of daytime thunderstorms and a 30 percent chance for nighttime thunderstorms. There is only a slight chance for thunderstorms on Sunday (Independence Day).
Temperatures: Today: 86/78, Thursday: 87/75, Friday: 90/75, Saturday: 91/75, Sunday: 92/75.
HAZARDOUS WEATHER: Scattered thunderstorms and numerous showers are expected today and tonight. Some of the thunderstorms will produce heavy downpours of rain, frequent lightning and gusty winds. Locally heavy rainfall is expected today and tonight. Numerous showers and thunderstorms will result in rainfall amounts ranging from 1 to 2 inches across many areas with localized amounts of 2 to 4 inches possible. A flood watch is in effect through Thursday morning for areas generally along and south of Interstate 12 in Louisiana and the Mississippi coastal areas. A coastal flood advisory is in effect today. Tides are expected to range from 1 to 2 feet above normal as moderate to strong southeast winds prevail across the north Gulf of Mexico. This may lead to minor coastal flooding during high tide today. A small craft advisory remains in effect for most of the Gulf coastal waters through tonight. Southeast to east winds of 23 to 30 mph are expected with seas up to 8 feet. Numerous thunderstorms are expected Thursday and scattered thunderstorms are forecast Friday through Tuesday. Some of the thunderstorms will produce heavy downpours of rain frequent lightning and gusty winds. Areas of heavy rainfall will be possible Thursday. Numerous showers and thunderstorms will result in rainfall amounts ranging from 1 to 2 inches across many areas with localized amounts of 2 to 3 inches possible. A flood watch is in effect through Thursday morning for areas generally along and south of Interstate 12 in Louisiana and the Mississippi coastal areas.


CENTRAL LOUISIANA: There is a 90 percent chance for thunderstorms today with an 80 percent chance for tonight. Tomorrow has a 70 percent chance daytime and 40 percent chance nighttime thunderstorms. Friday calls for a 50 percent daytime and 30 percent nighttime chance for thunderstorms. Saturday has a 40 percent daytime and 30 percent nighttime thunderstorm probability. For Sunday (Independence Day) there is a 40 percent daytime and 20 percent nighttime for thunderstorms
Temperatures: Today: 85/73, Thursday: 88/73, Friday: 92/74, Saturday: 90/74, Sunday: 91/73.
HAZARDOUS WEATHER: Outer rain bands associated with Hurricane Alex will sweep westward through the western upper Gulf coast states. Widespread rain with embedded heavy showers and thunderstorms can be expected. A flash flood watch is in effect for the coastal marshes and I-10 prairies. Long-period southerly swells associated with Hurricane Alex are generating a minor breaker run up at the coast resulting in an abnormal rise in water levels over and above the predicted astronomical tides. The actual tide levels this morning will be running from 3 to 3.5 feet above mean lower low water. The widespread rains will give way to more scattered showers and thunderstorms as the remains of Alex merge with a mid-west cold front which stalls across the Louisiana coastal waters.



NORTHERN LOUISIANA: There is a 60 percent chance for thunderstorms today with an 40 percent chance for tonight. Tomorrow has a 40 percent chance daytime and 20 percent chance nighttime thunderstorms. Friday and Saturday and Sunday (Independence Day) call for a 20 percent daytime and nighttime chance for thunderstorms.
Temperatures: Today: 91/71, Thursday: 92/72, Friday: 93/74, Saturday: 90/74, Sunday: 89/74.
HAZARDOUS WEATHER: A warm, moist tropical and unstable atmosphere will remain in place across much of the four-state region as Hurricane Alex wraps Gulf moisture across the area. This moisture along with daytime heating and a nearly stationary frontal system draped across northeast Texas and southwest and south central Arkansas will help produce scattered to numerous showers and thunderstorms. Due to the rich Gulf moisture, storms will be capable of producing very heavy rainfall with a quick one to two inches with totals up to near three inches in some locations. Ponding of water in streets, low lying and poor drainage areas can occur quickly. Gusty winds to near 30 to 35 mph along with deadly lightning will also be possible in and near thunderstorms. Isolated severe storms will be possible producing winds in excess of 58 mph but no watches are expected. The probability of widespread hazardous weather is low. Showers and thunderstorms will be possible across much of the area through the period mainly along and to the south of the Interstate 30 corridor with a majority along and south of the Interstate 20 corridor. The probability of widespread hazardous weather is low.

Temperatures: Today: 90/76, Wednesday: 88/76, Thursday: 87/75, Friday: 91/76, Saturday: 91/77.
HAZARDOUS WEATHER: A coastal flood watch is in effect today through Thursday as moderate east winds associated with strengthening tropical storm Alex results in above normal tides. Scattered showers and thunderstorms can be expected across the region between tropical storm Alex and an unusual late season frontal boundary settling south into the area. Heavy rains may accompany stronger storms.

The Atchafalaya River at Morgan City is currently at 4.26 feet (Minor flood stage). Minor flood stage is from 4 to 7 feet. The river is expected to rise to 4.5 feet by Monday and remain at that level at least through Tuesday. At 4 feet, water will move up the bank and across access roads below the city dock. Floodwall gates should be closed by the 5 foot stage to protect against higher stages. Vessel traffic will be affected by stronger river current and vessel traffic safety rules will be strictly enforced by the U. S. Coast Guard.

SOUTHEAST LOUISIANA: Today there is an 80 percent chance for thunderstorms, decreasing to 70 percent in the evening moving into Wednesday and Thursday. Thursday night into Friday and Saturday there is a 40 percent chance of thunderstorms.
Temperatures: Today: 87/77, Wednesday: 89/76, Thursday: 89/75, Friday: 90/75, Saturday: 91/76.

Tropical Storm Alex Update -June 28, 2010 - 4:30pm

The National Hurricane Center continues to forecast Tropical Storm Alex
to strengthen to hurricane status and move west northwest toward the
northeast coast of Mexico over the next several days. As of 4pm ...a
Hurricane Watch is in effect along the south Texas coast south of Baffin
Bay southward into northeast Mexico. Based on the current forecast, the
main affects of Alex in southeast Louisiana and south Mississippi are
anticipated to be the potential of locally heavy rainfall through
Thursday as tropical moisture moves northward into the area.. Rainfall
totals of 2 to 4 inches are expected over the next several days, with
locally higher amounts possible. A Flash Flood/Flood Watch may be
issued in later forecasts. In addition, east and southeast winds of 15
to 20 knots will cause tides to be 1 to 2 feet above normal along
coastal areas, with minor flooding of low lying coastal areas possible
at times of high tide. A Coastal Flood Watch is in effect to highlight
the potential of coastal flooding. Continue to follow the progress of
Tropical Storm Alex and local impact in southeast Louisiana and south
Mississippi by visiting the following web sites. National Hurricane

Temperatures: Today: 92/77, Friday: 94/77, Saturday: 92/77, Sunday: 93/76, Monday: 93/75.
HAZARDOUS WEATHER: An upper level low moving into northeast Texas today will still trigger showers and thunderstorms across interior southeast Texas as one or more disturbance brushes this area. Elsewhere, rain chances decrease markedly as you move further away from this upper level disturbance. Tonight, shower and thunderstorm activity will cease early due to the loss of daytime heating. Due to the high moisture content, locally heavy rainfall will be possible this evening. Rainfall rates will be 1 to 2 inches per hour which may cause some street flooding if this rainfall occurs over urban areas. Frequent cloud to ground lightning will also be possible. Friday through Wednesday the upper low will exit the region so rain chances will decrease and a more stable pattern will develop. Maximum afternoon heat index values from Friday into the weekend will range from 102 to 105 degrees.

The Atchafalaya River at Morgan City is currently at 5.27 feet (Minor flood stage). Minor flood stage is from 4 to 7 feet. The river is expected to remain at this level throughout the week. At 5 to 6 feet, the city dock may be under water. Water may cover the lower end of Belleview Front Street in Berwick. Vessel traffic may be affected by stronger river current and vessel traffic safety rules will be strictly enforced by the U. S. Coast Guard.

SOUTHEAST LOUISIANA: Today will be mostly sunny and partly cloudy in the evening. Friday through Monday has a 20 percent slight chance of thunderstorms each day.
Temperatures: Today: 94/76, Friday: 93/76, Saturday: 93/75, Sunday: 95/76, Monday: 93/74.
HAZARDOUS WEATHER: Heat index values will climb to around 105 degrees today and tomorrow afternoon, mainly for areas along and south of a line from metropolitan Baton Rouge to Hammond to New Orleans including the southeast Louisiana coast. A heat advisory remains in effect. Elsewhere across the area, expect afternoon heat index values to top out around 100 degrees. Isolated thunderstorms are expected mainly this afternoon across inland areas. While organized severe weather is not expected, some of the storms may become strong, with gusty winds to 45 mph, frequent lightning and heavy downpours. This weekend, heat index values will climb to near or above 100 degrees each afternoon across the area. Primarily afternoon and evening thunderstorms will be isolated in nature on Friday and into the weekend. Thunderstorms will become more scattered on Monday through Wednesday as a weak front advances toward the area. While organized severe weather is not expected, a few storms on Friday could become strong with gusty winds to 45 mph, frequent lightning and locally heavy rainfall.

CENTRAL LOUISIANA: Today has a 40 percent chance of thunderstorms with a decrease to 20 percent chance in the evening. Friday through Monday has a 20 percent slight chance of thunderstorms each day.
Temperatures: Today: 92/75, Friday: 95/76, Saturday: 96/75, Sunday: 96/74, Monday: 96/74.
HAZARDOUS WEATHER: An upper level low moving into northeast Texas today will still trigger showers and thunderstorms across interior southeast Texas as one or more disturbance brushes this area. Elsewhere, rain chances decrease markedly as you move further away from this upper level disturbance. Tonight, shower and thunderstorm activity will cease early due to the loss of daytime heating. Due to the high moisture content, locally heavy rainfall will be possible this evening. Rainfall rates will be 1 to 2 inches per hour which may cause some street flooding if this rainfall occurs over urban areas. Frequent cloud to ground lightning will also be possible. Friday through Wednesday the upper low will exit the region so rain chances will decrease and a more stable pattern will develop. Max afternoon heat index values from Friday into the weekend will range from 102 to 105 degrees.

NORTHERN LOUISIANA: Today has an 80 percent chance of thunderstorms during the day with an decrease to 50 percent in the evening. Friday through Monday has a 20-40 percent chance of thunderstorms each day.
Temperatures: Today: 84/73, Friday: 94/76, Saturday: 96/75, Sunday: 96/75 Monday: 95/74.
HAZARDOUS WEATHER: An upper level low pressure system will move slowly across northeast Texas into extreme southwest Arkansas by this evening. Additional rainfall amounts of 3 to 5 inches will be possible through the evening hours, resulting in significant flooding across portions of the area. As a result, a flash flood watch is in effect until 7 am Friday morning. In addition, strong to severe storms will be possible this afternoon and evening as this upper level disturbance combines with a moist and unstable air mass. The primary threat with the strongest storms will be damaging winds. However, brief isolated tornadoes will also be a concern. This severe activity should begin to die down this evening. Showers and thunderstorms will lift north of the area and mostly diminish on Friday.
