What this means:

Heavy rains and flash flooding and mudslides possible for the entire Dominican Republic. This is because the storm is so big – covering over 341 miles or 555 kilometers. Take note the DR is at most 241 km from north to south and 390 km from east to west. The alerts are in effect for the entire southern and northern coastlines of the Dominican Republic. Think big big storm! There are also warnings for Turks and Caicos islands (to the northern side of the island) and southeastern Bahamas.

The storm has slowed down, but is still moving fast at 31kph.

The weather forecasters now say the effects will be felt later in the day on Thursday.

The good news is that the pressure has kept to 1004 mb. This is up from 1000 mb yesterday afternoon. The forecasters say to watch the mb to know how much damage the storm will cause.

The forecast is no longer for the storm to enter via La Romana. It is now further to the west. This explains why there is no rain or wind in Santo Domingo at 4am on Thursday.

The NHC forecasters insist that people cannot focus on the track of the storm, rather on the size of the storm and the rainfall and wind hazards that will extend far from the center of the system.

The storm is forecast to be felt in the DR later in the afternoon of Thursday and Friday. Can go back to sleep and wait for the 8am forecasts.

South Coast
Mike Fisher’s last 2 updates;


TS Isaias is named.
on the 11PM/AST outlook the NHC shiftet the tracking forecast further West along the DR South Shores, which i think will continue as trend.
the Low pressure Center is South of PC on the western edge to move south of the Mona Passage.
what is seen as the Center is the strong portion which formerly was the SW part close to the low pressure center, there the storm's now actaul center formed.
the strong NE part is cut off the circulation, as a TS the storm will move for a while a smaller area than it did as a TD.
Tracking is still WNWwards, so i stick to my observations since this afternoon, that the tracking will keep shifting westwards along our south coast.
what could tell me lies would be a steep slow down on forward speed to get in a good shaped round form, which it actually isn't. now its strongest portion is close to the new center on its SE, but that is only temporarily, a storm in transition.
it could be, that due that transition, the Center seems to not move for a couple hours/seem to be stuck south of PR, while Center and that SE quadrant get together to form a nice and strong Round shaped TS Center piece.
Time for a nap for me here on the East.
people all along our South should keep watching,
as such thing approaching could any time change direction and just hop ashore anywhere along our south shores.
stay home, locked in and dont care for what ever happens outside


TS Isaias formed it's center nicely during the last hours and that brought it closer to PR and DR, it ison 17.2N right south of the Mona Channel. while we are here in PC already in the windfield, by now it was just on/off of some gusting phases.
max winds are on 60mphr and it is steaming on quick 20mphr forward to NW, pointing for our SE/SCentral coastline.
time for an other nap while listening to the rain.

Reports from Puerto Rico are of power outages, strong wind gusts and lots of rain. This should be coming soon to the DR. Onamet reported early morning that the wind gusts have increased to 95kph. Santo Domingo awoke to just cloudy skies. No one should trust this storm to be kind.

According to the NHC 8am advisory nothing much has changed. Everyone should still prepare for wind gusts and heavy rains in the Dominican Republic. Isaias is now located near latitude 17.6N and longitude 68.5West and moving toward the northwest near 20 mph (31 km/h). It is still moving forward fast, that is good news for this country.

The forecast is for the storm to come inland around 2pm. Onamet is alerting to continuously monitor the entire east to south coast. It could enter as far west as Pedernales, but this needs to be closely monitored.

NHC says that on their forecasted track, the center of Isaias is scheduled to "move over Hispaniola later today" and upwards towards southeastern Bahamas by tonight or early Friday. The storm's forward speed is expected to slow after it leaves the DR.

Maximum sustained winds have increased to 60 mph (95 km/h) with higher guests.

NHC reminds all that the tropical storm force winds are extending outward up to 415 miles (665 km) from the center. Take note south to north of the DR is only at max 265 km.

People should continue to monitor what is happening in Puerto Rico to get an idea on the conditions to expect here later in the day. Wind gusts of 87 km/h have been reported there.

Also on the positive side the estimated minimum central pressure has not dropped. As of the 8am report it was at 1003 mb.

So far not all that bad in sosua. It's quite bright out but there are dark water laden clouds everywhere. It is breezy with some gusts. But nothing strong enough to pick anything up and throw it across the yard. Haven't checked where the majority of the storm is located now. Trying to get through DR1 first. Power went off a couple of times during the night but I expect that was caused elsewhere on the island and just affected us. Not wanting to jinx anything but if it stays like this for the rest of the day it will just be a blustery day with intermittent showers. Something Edenorte should be able to handle without plunging the province into a blackout - I hope. Time will tell it's still early and we have all day to get through before the storm will be moving on, at least that was the case with what I read last night. Don't yet know bout today's foretasted reality.

Let me remind people how storms work. From past experience through storms.... and this will apply to Isaias because it is so big. There are these outer bands that act as if a person were spinning around with arms outstretched and slapping everything in the way. Those are the wind gusts. That is how one property can be destroyed, another untouched. Those outer bands are what will be affecting the Dominican Republic. So some parts of the country could be hit by wind gusts of 75+ km/h. Remember... prepare for the worse and stay safe.

Gloria Ceballos, the Dominican Republic's weather chief, tweeted just now, sharing an image of the NHC:

Infrared image of 8:10am of the TS Isaiah moving at about 31kph, with maximum sustained winds of 95kph, whose center is located about 175kms east/southeast of Santo Domingo.

The forecast continues to be that it will cross the island and be impacted by the Central Mountain Range. Years back there was Hurricane Frederick (1979) that came after Category 5 Hurricane David and parked itself in the Central Mountain Range. This is a tropical storm, not a hurricane. But this may be the biggest storm to pass our way in years.
