Tropical Cyclone 09L (Harvey) is located about 30 miles south-southwest of Memphis, Tennessee – Final Advisory
Tropical Cyclone 10L (Irma) is located about 775 miles west of Cabo Verde Islands
Tropical Depression Harvey has moved out of Texas, with heavy rains spreading northeast through the lower Mississippi Valley, and on into the Tennessee Valley…and has been given its Final Advisory
Harvey was a Category 4 hurricane when it made landfall for the first time late this past Friday.
Harvey was heading inland as a weakening tropical depression today, although the death toll from its impact rose again, as authorities in Houston began a recovery that could last months.
The storm has killed at least 35 people thus far, and the death toll was rising as bodies were found in receding waters. Some 32,000 people were forced into shelters around the U.S. energy hub of Houston since Harvey came ashore on Friday…as the most powerful hurricane to hit Texas in a half-century.
“At the end of the day, this is likely to be the largest natural disaster by property damage in history,” said former Houston Mayor Bill White.

According to the National Hurricane Center (NHC),
AT 400 PM CDT...2100 UTC...THE CENTER OF TROPICAL DEPRESSION HARVEY WAS LOCATED NEAR LATITUDE 33.8 NORTH...AND LONGITUDE 90.5 WEST. TROPICAL DEPRESSION HARVEY IS MOVING TOWARD THE NORTHEAST AND IS EXPECTED TO CONTINUE THIS MOTION OVER THE NEXT 48 HOURS. THIS FORECAST TRACK TAKES HARVEY THROUGH THE TENNESSEE VALLEY ON THURSDAY NIGHT AND FRIDAY, AND MOVING INTO THE OHIO VALLEY STATES ON FRIDAY NIGHT AND SATURDAY AS A POST-TROPICAL LOW.
HAZARDS AFFECTING LAND:
TROPICAL DEPRESSION HARVEY IS EXPECTED TO PRODUCE 2 TO 5 INCHES OF RAIN FROM WESTERN TO CENTRAL TENNESSEE AND WESTERN TO CENTRAL KENTUCKY INTO EXTREME SOUTHEASTERN INDIANA, SOUTHERN OHIO AND WEST CENTRAL WEST VIRGINIA. LOCALLY HIGHER TOTALS OF 6 TO 8 INCHES ARE POSSIBLE FROM WESTERN TENNESSEE TO WEST CENTRAL KENTUCKY. THESE RAINS WILL ENHANCE THE FLASH FLOODING RISK ACROSS THESE AREAS. HOWEVER, WIDESPREAD FLOODING WILL CONTINUE IN AND AROUND HOUSTON, BEAUMONT/PORT ARTHUR/ORANGE, AND EASTWARD AROUND THE LOUISIANA BORDER THROUGH THE WEEKEND. THE EXPECTED HEAVY RAINS SPREADING NORTHEASTWARD FROM LOUISIANA INTO WESTERN KENTUCKY MAY ALSO LEAD TO FLASH FLOODING AND INCREASED RIVER AND SMALL STREAM FLOODING. DO NOT ATTEMPT TO TRAVEL IN THE AFFECTED AREA IF YOU ARE IN A SAFE PLACE. DO NOT DRIVE INTO FLOODED ROADWAYS.

Hurricane Irma remains active in the Atlantic west of the Cabo Verde Islands, and is now a Category 3 major hurricane…although is no immediate threat to land
Irma has strengthened over the eastern Atlantic to become the 4th hurricane of the 2017 Atlantic hurricane season, according to the U.S. National Hurricane Center.
It’s currently a Category 3 storm, although Irma’s winds could intensify to 120 mph over the next few days, pushing the hurricane to Category 4.
Satellite imagery showed Irma with a pronounced eye today, and maximum sustained winds had increased from 50 mph to 100 mph in just 24 hours…as of late Thursday morning.
Irma will take about a week to trek west across the Atlantic Ocean, with a possible landfall over the Leeward Islands in the northeastern Caribbean…to the Carolina’s and Bermuda – it’s too early to know at this point.
According to the National Hurricane Center (NHC),
Irma has become an impressive hurricane with intense eyewall convection surrounding a small eye. Satellite estimates continue to rapidly rise, and the Dvorak classifications from both TAFB & SAB support an initial wind speed of 100 kt. This is a remarkable 50-kt increase from yesterday at this time. Microwave and satellite data suggest that an eyewall replacement cycle could be starting. This isn't surprising given how small the eye is, and will probably be the first of many eyewall cycles for this hurricane. Overall, Irma should be in a low-shear environment for several days, with the intensity controlled by eyewall cycles and the moderately warm SSTs along the path. Thus the forecast intensity is leveled off for the next 2 days. After the weekend, Irma should be moving over much warmer water, with SSTs forecast to be 29C at the end of the period. All indications are for Irma to be strengthening by the end of the forecast period, with the NHC prediction adjusted slightly upward from the previous one, in line with the extremely low pressures forecast by the global and regional hurricane models at that time. Irma continues moving west-northwestward, now at about 10 kt. There has been no change to the forecast philosophy, with the hurricane likely to turn westward and west-southwestward over the next few days due to a building ridge over the central Atlantic. At long range, however, model guidance is not in good agreement on the strength of the ridge, resulting in some significant north-south differences in the global models. I am inclined to stay on the southwestern side of the model guidance, given the rather consistent forecasts of the ECMWF and its ensemble. In addition, the strongest members of the recent ensembles are on the southern side on the consensus, giving some confidence in that approach.
