The heaviest rain will fall to the west of the track which consists of most areas west of I-95. There could be as much as 2-to-4 inches of rains in parts of our area through midday Friday. Flash flooding is possible across all of southern New England particularly in the 6-to-10 hours of Elsas closest pass on Friday morning.
Wind gusts 35-to-55 miles per hour are likely to the east of I-95 in Mass. Farther southeast over severe southeastern Mass. and the Cape/Islands, winds could gust 55-to-70 mph out of the south-southeast.
BOSTON (CBS)– The whole east and southeast part of Massachusetts are under hurricane warnings for Tropical Storm Elsa

While Elsa will be a quick mover from mid-morning to mid-afternoon Friday, there are a number of reasons for concern in our location.

TRACK: Tropical Storm Elsa.
Heres what to expect:.
RAINS:.
The heaviest rain will be up to the west of the track which includes most locations west of I-95. There could be as much as 2-to-4 inches of rains in parts of our area through midday Friday. Flash flooding is possible across all of southern New England particularly in the 6-to-10 hours of Elsas closest hand down Friday early morning.

WINDS:.
The strongest winds will be to the east of Elsas track which is likely to consist of the immediate coastline of the South Shore and definitely Cape Cod and the Islands.
( WBZ-TV).
In this zone, there is a hazard for tree and power line damage and numerous power failures. Wind gusts 35-to-55 mph are most likely to the east of I-95 in Mass. Farther southeast over severe southeastern Mass. and the Cape/Islands, winds might gust 55-to-70 mph out of the south-southeast.
COASTAL WATERS:.
While we dont anticipate much storm surge or seaside flooding with Elsas passage, the seas will be very angry with swells 10-to-20 feet simply offshore, particularly on our south dealing with beaches along the South Coast. Unsafe rip currents and marine conditions will exist for many of the day Friday.
TIMELINE:.
The heavy rain blood circulation directly related to Elsa will be moving into southwestern New England around 7 a.m. Expect the brunt of the rain and wind from Elsa in between 7 a.m.-2 p.m. on Friday.
For about a 6-to-8 hour period we will remain in and out of torrential rainstorms, receiving as much as 2-to-4 inches of rainfall in just a brief time period. Anticipate some street and flash flooding Friday early morning with some roadways ending up being flooded and nearly impassable.

The greatest winds (in extreme eastern Mass., Cape, Islands) will take place between 7 a.m. and 4 p.m. on Friday as Elsas center trips up and over our location. Once again, south-southeast gusts as high as 55 miles per hour are likely across this whole location with the capacity for a few up to 70 mph on the Outer Cape and Islands.
With tropical systems passing near or overhead, there is constantly an enhanced risk of severe weather, perhaps even a separated twister. This is something else we will be carefully seeing on Friday.
The rainfall will rapidly shut down throughout the afternoon from south to north and nearly the entire rain structure will be up in Maine after 1-to-2 p.m. and rapidly racing northward toward Canada. The winds will remain gusty along the coast for a few extra hours, through about 4-to-5 p.m. before reducing.
We will get quick clearing Friday evening and aside from a few roaming showers, we have a fairly good weekend ahead with temperature levels near or slightly above 80 degrees. Just what the doctor bought after a really hectic, wet week of weather condition.
