This was stated by the meteorology technician and forecaster of the OHMC (Hydro-Meteorological Observatory of Córdoba) Rafael Di Marco. “We are going to have a third heat wave, which is going to be very marked on Thursday, Friday, Saturday, Sunday and Monday, and possibly until Tuesday,” he said.
According to the adviser, almost the entire province of Santa Fe “is going to have temperatures in the order of 40, 42 and in some places 44° Celsius”, so “the evapotranspiration that we are going to have will be terribly marked” and the few millimeters of the last rains will be lost quickly. “What falls is lost in hours or days.” He also estimated that, at least until mid-February, it could be “the last wave of heat”; and perhaps the last of the summer.
For this Tuesday, January 3, he estimated the possibility of some instability in the center-south of Santa Fe, but “you don’t have to wait for a long millimeter; if something falls, it is welcome.” He explained that the “instability” category implies “very low” chances of precipitation.
After the heat wave, on Tuesday, January 10, “a relief of precipitation could arrive, but let’s not expect it to be much either.” The center-north of Santa Fe would benefit more, while the south would have some rain the following week (third of the month).
“We have projected little water for the first 15/18 days of January; after that, the rainfall regime would tend to normalize.” It is not a question of a certainty, she clarified, but of a tendency of changes in the atmosphere “typical of the time and the exit of the Niña.”
Di Marco maintained that a Niño year would begin around July/August, as anticipated by the NOOA. Although “I do not rule out that we have a rapid entry of El Niño and perhaps we can see differently to the fine,” he ventured.
