Heat indexes are anticipated above 100 degrees Fahrenheit this Friday

He National Meteorological Service (SNM) in San Juan anticipated that the heat pattern that was registered yesterday in various sectors of the island could be repeated today, Friday, in coastal and urban areas, where heat indexes are registered above 100 degrees Fahrenheit (ºF) .

However, the meteorologist Carlos Anselmi told The new day that in areas such as, for example, the north of the island, cooler and more stable conditions could be experienced because, unlike yesterday, today the wind direction changed and this will bring cooler air to the local area.

“In the northern area the conditions should be a bit cooler because the wind is from the northeast. However, high heat indices are expected as in the low and middle 100 (ºF). The hottest conditions are expected in the west and south of Puerto Rico “, detailed the expert.

Anselmi stressed that the change in wind direction implies, in turn, that the rains generated this afternoon, due to the combination of local effects, will be concentrated in the towns of the south, southwest and parts of the interior of the island.

“The rain activity of the day, although more periods of sunshine are expected, the formation of thunderstorms in the afternoon cannot be ruled out for the interior and southwest of Puerto Rico,” he said.

The meteorological agency established in its weather perspective that from the interior to the southwest all areas are at risk of thunderstorms and urban floods, because the soil is already saturated.

The main reason behind the thunderstorm rains is the combination of local effects such as sea breezes and daytime heat, along with humidity in the area that remains at high levels, according to SNM.

In fact, The combination of these factors keeps the SNM experts in a process of analysis after yesterday they received a report from a person who indicated that strong winds, the product of a thunderstorm, detached a zinc roof on a house in Bayamón, at the same time in which they also caused a large tree to fall to the ground.

The facts are investigated by the meteorological agency to validate if it was a tornado or a strong thunderstorm that produced winds.

Meanwhile, Anselmi indicated that the maritime conditions are “calm” with waves below four feet.

“The winds are expected to be around 10 knots and so far the risk of ocean currents seems to indicate that it will remain low. Although it is important to emphasize that the shape of the beaches could produce some rotations near rocky areas or have some breakwaters where currents are observed. So be very careful, “said the meteorologist.
