the west-southwest near 14 mph (22 km/h). A turn toward the west
is expected later today, followed by a west-northwestward turn late
Tuesday. On the forecast track, the center of Irma will move near
or over portions of the northern Leeward Islands Tuesday night
and early Wednesday.

HAZARDS AFFECTING LAND
STORM SURGE: The combination of a dangerous storm surge and large
breaking waves will raise water levels by as much as 6 to 9 feet
above normal tide levels along the coasts of the extreme northern
Leeward Islands within the hurricane warning area near and to the
north of the center of Irma. Near the coast, the surge will be
accompanied by large and destructive waves.
WIND: Hurricane conditions are expected within the hurricane
warning area by Tuesday night, with tropical storm conditions
expected by late Tuesday. Hurricane conditions are possible within
the hurricane watch area by late Wednesday, with tropical storm
conditions possible by early Wednesday.
RAINFALL: Irma is expected to produce total rainfall accumulations
of 3 to 6 inches across the Leeward Islands, with isolated maximum
amounts of 10 inches across the northern Leeward Islands. These
rainfall amounts may cause life-threatening flash floods and
SURF: Swells generated by Irma will affect the northern Leeward
Islands during the next several days. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
As far as our weather is concerned we are enjoying a beautiful late summer day on this Labor Day with sunshine and temperatures into the 80s for the afternoon highs. There is no rain anywhere close and very little cloud cover. There are no weather issues to speak of on this last day of the holiday weekend.
LOCAL RADAR NEW YORK CITY
Tonight will be a warm night with lows in the 60s to near 70 with nothing more than a few passing clouds. Tuesday looks to be very warm with sunshine and highs in the mid to upper 80s. Then a cold front approaches on Wednesday with the chance for showers and thunderstorms. That front starts to set in motion the mechanisms that will determine the fate of Hurricane Irma.
