Matthew now a Category 3 hurricane in the Caribbean

Matthew rapidly intensified overnight in the Central Caribbean. Winds are now 115 mph and it is
forecast maintain this strength for the next few days.  It is battling some wind shear, but that hasn't weakened the storm.

There is a ridge of high pressure to the north of Matthew that is steering it to the west to WSW for the next day or so with a slower forward speed.  Then the ridge will weaken over the Atlantic, and a trough of low pressure will move over the Gulf of Mexico and Eastern U.S. This will cause Matthew to turn to the north, and head toward Jamaica, Haiti and Cuba.  However, there is some disagreement with the forecast models as to where and when it will turn to the north.  The ECMWF (Euro) and the UKMET show it more to the east and the GFS and other show it a little more to the west. The NHC has taken a middle of the road approach to the model spread.  This shows it moving just east of Jamaica early Monday Morning and over Eastern Cuba early Tuesday Morning. Then it will move over the Bahamas.

At the same time, the wind shear is forecast to be weaker and it will be moving over very warm water.  This will allow Matthew its major hurricane or Cat. 3 status with 115 mph winds as it moves by Jamaica and makes a landfall over Eastern Cuba next week.

Now the question is how fast will Matthew be moving, and where will it go once it emerges off Cuba.  The forecast models are not in agreement at this time. The latest trend seen in the spaghetti plots show that the hurricane will likely move to the north and be east of Florida. Then continue northward toward the Outer Banks of North Carolina and then turn out to sea.  However, since there is a lot of uncertainty, there is little confidence in the extended forecast.

I can't rule out Matthew impacting the Eastern Gulf of Mexico, but it is looking less likely at this time. One great thing we have going for us is that another cold front is forecast to move through late next week, and IF Matthew would head toward the Gulf, the front would keep Matthew in the Eastern Gulf.  Again, I can't totally dismiss the Gulf yet, but it is looking less likely of that happening!  Once it makes the northward turn, then we will have a better feel of where it will be going.

Needless to say, we will still keep a close eye on the evolution of the hurricane.  Stay tuned for updates. -Dave

Comparison between Hurricane Matthew's possible forecast track loop vs Hurricane Betsy's

Some of you have been calling to say that Matthew's forecast to do a loop in the Atlantic Ocean off the SE U.S. is the same as what Hurricane Betsy did back in 1965. Well...that is not true. Betsy formed on August 27, 1965 just off the Leeward Islands. It quickly became a tropical storm on the same day, and then became a hurricane on August 29.  It made a few loops in its track with one north of Puerto Rico and a second north of the Bahamas.  There is a strong area of high pressure that was preventing Betsy from moving to the north, and that is what caused it to loop.  After the second loop, it then moved SW across the Bahamas, then turned west to move over far South Florida and then into the Gulf.  It eventually turned to the NW and quickly tracked right to New Orleans where it made landfall as a major hurricane on September 9th. Hurricane Matthew formed in the Atlantic east of the Leeward Islands as a tropical storm on September 28. It quickly moved west into t...

The Great Flood of 1983

It was 30 years ago that the Baton Rouge area experienced what is likely the worst flood in its history!  On April 5-9, 1983 we were hit with 6 to 13 inches of rain from a slow-moving storm.  This rain quickly ran off into the Amite, Comite, Tickfaw and Tangipahoa River Basins.  Some of the highest rainfall totals were in the headwaters of the Amite River in the Felicianas and South Mississippi.  Also, there were some strong easterly winds which slowed down the water from draining into Lake Maurepas and Pontchartrain.  These were some of the reasons why the flooding occurred in Baton Rouge & Denham Springs.  The weather map to the right shows the weather for April 8, 1983. A stalled front over the Southeast U.S. lead to the heavy rain event and flooding. The rivers quickly rose and spilled out of their banks.  The rain didn't stop, so the water continued to rise and rise.  Rivers rose to what are still the record levels.  The Amite in D...

Flash Flood Watch now until Thursday Evening for WBRZ Viewing Area

The NWS in Slidell, LA has issued a  Flash Flood Watch for all of the WBRZ Viewing Area starting now and continuing until Thursday Evening. Rain has been falling for the last few hours and we have already picked up over 1.30" in Baton Rouge.  This is WAY more than the forecast models were predicting for this time.  The area of low pressure continues to develop over South Texas and a warm front will move up from the Gulf of Mexico by Wednesday Morning.  This will spread widespread rain and a few thunderstorms over Southern Louisiana all night and into Wednesday.  Then it looks like we will taper off the rain to just scattered showers during the day on Wednesday. On Wednesday Night, a cold front will move out of Texas into Louisiana.  As this happens, a squall line of thunderstorms is expected to move ahead of it and through Baton Rouge on Thursday Morning.  Some of these storms could be strong to severe with damaging winds and a few tornadoes. ...
