Heavy Rains and Gale Winds along Florida Coast

A gale low over the northeastern Gulf of Mexico will move slowly east bringing beneficial rains to drought-stricken areas of the central and eastern Gulf Coast. A secondary low center will form along the Florida East Coast early Thursday and will produce some heavy rainfall in southeast Florida from West Palm Beach and Fort Lauderdale down through Miami and Homestead. In addition, strong to gale force winds are likely with seas building 3-5 meters (10-16 Feet) north of the developing secondary low center Thursday.

NOAA WPC Surface Forecast Wednesday Night

Extremely heavy rainfall rates are possible which may approach or exceed 2 to 3 inches per hour and may produce rainfall totals upwards of 3 to 6 inches with some isolated max amounts approaching 10 inches.

A Second Hurricane-Force Storm heads for English Channel Approaches

NOAA OPC Surface Analysis

A 2nd rapidly deepening storm low east of Newfoundland will move east then east-southeast with winds to 65 kts building significant wave heights to 14 meters (46 feet) during the next 36 hours over the eastern North Atlantic north of the Azores.  Thereafter the low will begin to weaken and move across southern England into the North Sea.

NOAA OPC Surface Forecast 1200Z 04 November

Again ship delays are likely for both inbound and outbound English Channel traffic as well as north and southbound traffic in the Bay of Biscay.

Hurricane-Force Storm to affect Bay of Biscay and English Channel Approaches

NOAA OPC Surface Forecast 1200 UTC 31 October

A low pressure disturbance will move off the New England coast early Monday, moving rapidly ENE deepening to a gale low south of Newfoundland then deepening rapidly into a hurricane force storm reaching the English Channel Approaches by 0000 UTC November 2nd with winds of 65-75 kts and significant wave heights building to 12-14 meters (40-46 feet) over the Bay of Biscay and Channel approaches.  This will likely cause issues, particularly with westbound shipping.

Catastrophic Cat 5 Otis makes landfall near Acapulco

Cat 5 Hurricane Otis making lanfall near Acapulco, Mexico

Major Hurricane Otis continued to strengthen until near the time of landfall in southern Mexico near Acapulco, reaching a catastrophic Category 5 with max wind of 145 kts (165 mph). 

 

 

 

 

Otis intensified very rapidly from a tropical storm to a Cat 5 hurricane in about 18 hours as it moved over sea surface temperatures from 28 C to about 30 C as it approached the coast.  Although the SSTs are warm, they are not all that unusual for the area. The very rapid intensification will be a subject for further study.  In 2015  Hurricane Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours with max winds of 185 knots (215 mph) but weakened to 130 kts (150 mph) at landfall. 

Otis has moved onshore in the greater Acapulco area and now that the center is moving inland, rapid weakening is expected.

Hurricane Otis nearing Cat 5 Strength

NOAA IR Satellite Image Hurricane Otis

Hurricane Otis is undergoing very rapid development with max winds currently at 125 kts with a min pressure of 941 mb and significant wave heights estimated 12-13 meters (40-43 feet) as it moves NNW at 7 kts. Otis is a small but powerful storm with hurricane force winds extending outward 20-25 nm and 50 knot winds outward 30-40 nm   Otis is forecast to peak near 140 kts (Cat 5) tonight, prior to landfall.  

NHC Forecast Track for Hurricane Otis

 

Otis is forecast to be a catastrophic Category 5 hurricane when it reaches the southern coast of Mexico late tonight or early Wednesday. Heavy rains from Otis will continue to impact areas of southwest Mexico this week.  This rainfall will produce flash and urban flooding, along with mudslides in areas of higher terrain.

Tropical Storm Otis continues to Develop south of Acapulco

NOAA TS Otis Satellite Image

Tropical Storm Otis continues to become better organized SSE of Acapulco, Mexico as it moves NNW at 7 kts. Max winds are now at 60 kts with significant wave heights estimated near 7 meters (23 ft). Otis is forecast to continue NNW and should cross the coastline of southern Mexico in a day or so with max winds about 80 kts. The interaction of the circulation of Otis with the mountainous terrain of Mexico could induce a slight leftward turn as the system nears the coastline.

NOAA NHC Track Forecast for TS Otis

 

 Otis is forecast to become a hurricane before it reaches the southern coast of Mexico late tonight or Wednesday, and hurricane and tropical storm conditions are expected along portions of the southern coast of Mexico where hurricane and tropical storm warnings are in effect. Heavy rains from Otis will begin to impact areas of southwest Mexico early this week.  This rainfall will produce flash and urban flooding, along with mudslides in areas of higher terrain.

Tropical Cyclone Lola over South Pacific has reached max winds of 120 knots

Tropical Cyclone Lola Satellite Image

Tropical Cyclone Lola over the South Pacific NNE of Port Vila, Vanuatu has intensified to 120 kt max winds with significant wave heights to 15-15.5 meters (about 50 ft) as it moves SSW at 6 kts. Lola has likely reached its peak intensity as it moves over cooler sea surface temperatures and into an area of strong vertical wind shear.

JTWC Track Forecast for TC Lola

 

Lola will likely weaken as it approaches and moves over the Islands of Vanuatu and then should turn southward towards New Caledonia as a weakening tropical storm.
