Ernesto reaches hurricane strength as it approaches the Yucatan

By: Angela Fritz , 8:55 PM GMT on August 07, 2012

Ernesto strengthened to a category 1 hurricane this afternoon after the morning hurricane hunter mission found winds of 80 mph, which is unusual for a hurricane without an eye wall. The hunters also found a minimum central pressure of 984 mb, which has dropped since this morning. The next hurricane hunter mission is scheduled to reach the center of the hurricane around 8pm EDT. The rain bands from Ernesto have reached the coast of Belize and Mexico as it continues to move west along the coast of Honduras, and landfall is expected north of the the Belize/Mexico border tonight around midnight. The Yucatan Basin buoy is now reporting gusts up to 53 mph, with sustained winds around 40 mph and 19 foot waves. These gusts are about 10 mph stronger than this morning's readings. Weather stations along the coast of Mexico and Belize aren't reporting winds stronger than 10 mph, however, they are expected to pick up around 8 or 9pm EDT tonight. The island of Roatan in Honduras is experiencing winds around 15 mph this afternoon, along with some light to moderate rainfall. Honduras seems to be the most impacted country so far, although they have avoided issuing evacuations. Nicaragua, however, has evacuated 1,500 people as of last night, and Mexico's authorities have evacuated around 600 residents from Punta Allen, which is a fishing village between Cozumel and Chetumal.

Visible satellite imagery suggests Ernesto still has the potential to develop an eye wall before landfall, as strong, organized thunderstorms are present in all four quadrants of the hurricane. Infrared satellite imagery shows the clockwise circulation at high levels (the upper level anti-cyclone) which will help ventilate the hurricane and could support further enhancement. If Ernesto wasn't approaching landfall, it would likely continue to strengthen and could have even experienced a period of rapid intensification, given the heat content of the Caribbean Sea. Wind shear around the hurricane remains low at 5-10 knots.

Forecast for Ernesto
Ernesto will continue to track west this afternoon and evening, making landfall north of the Belize/Mexico border around midnight tonight. Given the current state of the hurricane, some more intensification is possible over the next few hours as it approaches land. Heavy rains continue to be the main threat from Hurricane Ernesto. The Hurricane Center is forecasting 4 to 8 inches of rain to fall, increasing in the higher elevation of Belize. After landfall, the storm will take about a day to cross the Yucatan, and the terrain will diminish its winds. Once Ernesto re-emerges over water into the Bay of Campeche in the southern Gulf of Mexico, wind shear will be light and ocean waters warm with high heat content. Ernesto is then expected to redevelop some strength and potentially regain hurricane status while over water, which a few of the models are suggesting. Second landfall will probably occur Friday morning around Veracruz, Mexico, but could reach land anywhere from Tuxapan to Coatzacoalcos.

True. We've seen many beautiful and robust lows with hefty model support step magnificently off of Africa's west coast, only to dissipate into a bunch of scattered rainstorms within 24 hours of touching the water. You might want to give them a day or two before plotting U.S. landfall locations and times...
But then we have seen storms form right over Africa and come off and immediately develop with model support..Julie 2010 comes to mind :).

was that a pinhole on ernesto?
Any wind reports, damage reports?
Seems like a very small eye and a nice eyewall and CDO If ernesto had had more time would have been a major in no time...might have even been stronger at landfall than the 85mph they gave it...

Will it even make it back in?


It's done. I see very little chance of this making it back over water and even if it does, at best it will only get half its core over water again. We saw this developing last night when it took that hard left turn. It took it's toll on the core and it not gaining any more latitude obviously ended up being it's death sentence.

It's going to be interesting to see what the post analysis is of Ernesto. He had a satellite presentation of a CAT 3 after landfall. He was probably rapidly intensifying as he was making landfall. I still think he was a round a 90 knot to 100 knot storm at max intensity.

This is true. The Canadian Maritimes have been nailed repeatedly by huge storms..Tropical and non tropical. Igor fresh in the minds of many. WIKI..Hurricane Igor was the most destructive tropical cyclone to strike the Canadian island of Newfoundland on record. Igor originated from a broad area of low pressure that moved off the west coast of Africa on September 6, 2010. Tracking slowly westward, it developed into a tropical depression on September 8 and strengthened into tropical storm shortly thereafter. Higher wind shear temporarily halted intensification over the following days. On September 12, explosive intensification took place, and Igor reached Category 4 status on the Saffir–Simpson Hurricane Wind Scale. By this time, Igor had already begun a prolonged turn around the western periphery of the subtropical ridge. Peaking with winds of 155 mph (250 km/h), the cyclone began to enter an area unfavorable for continued strengthening, and Igor gradually weakened before brushing Bermuda as a minimal hurricane on September 20. After turning northeastward, the system began an extratropical transition, which it completed shortly after striking southern Newfoundland. The remnants of Igor were later absorbed by another extratropical cyclone over the Labrador Sea on September 23.
