Tropical storms Boris and Cristina could dump huge amounts of rain from Nicaragua up through Mexico this week.
Transcript
00:00Well, we have two named storms in the Pacific. One of these is just about to make landfall
00:05this evening. Another one will be bringing more of a significant risk of flooding throughout
00:10the course of the week on the Pacific side of Mexico. Is anything cooking in the Atlantic?
00:16Well, at face value, no, although we'll look at some prospects there as well. The risk
00:21in Atlantic development, risk of Atlantic development is down a little bit, but we
00:26have lots to talk about here in the Pacific. And some of this is going to bring some potentially
00:29life-threatening flash flooding to some parts of Mexico. Let's take a look at the map here.
00:34And overall, we have Boris and we have Christina. Boris to the west and Christina farther southeast.
00:41You can see a deep plume of convection here from Christina earlier today. Boris is continuing
00:47to churn and will be making landfall this evening and tonight. And again, if you look closely,
00:53you may say, well, what's up with the center of the circle? It seems a little east. A lot
00:58of deep convection to the west, but if you look closely near the end of this loop, there
01:02you can find the low-level circulation in the low-to-mid clouds there near the nucleus
01:08of the storm. That's Boris. And again, Christina, kind of a newcomer here, was Tropical Depression
01:153E earlier. But now we are dealing with two named storms on the map. And actually, Christina's
01:20on the map as well. So we can actually, as of today, we can highlight Christina in red
01:25as well. Check it off the list. So the East Pacific is pretty active right now. Here is
01:32Boris. And I'm going to make myself disappear there. We expect Boris to make landfall this
01:37evening. And again, this is going to be bringing some flooding to parts of the Mexican coast.
01:42But just as quickly as it comes in, Boris, look at the mountainous terrain here over the
01:48area here. We're going to see this lose its intensity and integrity. And it's going to
01:54become a storm that basically just becomes a tropical rainstorm raining out over the mountains.
01:58In the short term, though, a quick look at Boris' storm surge, a one- to three-foot storm
02:02surge here southeast of Acapulco. But wind potential here, somewhat modest. 40- to 60-mile-per-hour
02:09gusts in Acapulco when it comes to the largest population center in the area. And rainfall
02:14amounts tied to Boris. Now, this is wrapping up Tuesday, four to eight inches. But keep
02:20in mind, we've got another storm behind this one. It's going to bring some very heavy rain
02:24to the same area. So it's a one-two punch. And again, this is from a timeline from yesterday,
02:29Sunday, Monday, and Tuesday, four to eight inches there in Acapulco. But regarding the overall
02:35AccuWeather, Real Impact Scale rating for hurricanes for Boris, we're looking at a less
02:41than one here in Mexico because this storm is, again, a lower-end tropical storm. And we don't
02:49expect it to do anything too surprising here. But flooding is certainly the concern. Going
02:54back to the satellite loop, just to go from Boris to Cristina. Cristina is a storm that's
02:59going to be a problem all week long. And as we bring you into the wind forecast associated
03:06with Cristina, this storm will likely ramp up a little more because it is just offshore
03:12and it'll have more time to strengthen offshore. And here we're actually going with, again,
03:17a 60- to 80-mile-per-hour wind gust potential for parts of extreme southern and southeastern
03:23Guatemala and other areas here in some portions of perhaps the coast of, well, areas southwest
03:29of Honduras there on the Pacific side. Now, I want to point out the arrival times here,
03:37the arrival times in that dashed line there. And really, the gradual northwestward push here
03:46is going to crank the wind up after 7 p.m. on Tuesday. That's going to be the strongest wind
03:51time frame Tuesday night through Wednesday and Wednesday night. That's when we become most
03:55concerned about the gusts of wind 60-80 miles per hour here in many areas. And overall, areas
04:03like El Salvador will be facing some of that risk for some of the stronger winds. That will be a
04:08big
04:09concern here along the coastline Tuesday night and Wednesday. But overall, the strongest, greatest
04:16potential for flooding will come from Cristina over the course of the whole week here, 8-12 inches
04:21of rain. And you'll notice, if there is any good news in this, if there is any good news, most
04:26of
04:27the Boris rain is generally adjacent to and west of the footprint of this one. So this is impacting
04:32a different area from San Salvador, El Salvador, into the far southeastern parts of Mexico and areas
04:39like southern parts of Guatemala as well. Also, from Managua West and western parts of Nicaragua,
04:44we're going to see some of that heavy rain, 8-12 inches as well. So overall, this storm has a
04:48more
04:48escalated accu-weather real impact scale rating of 1 for both Mexico and Central America.
04:54Gusty winds, flooding rain, and mudslides. Let's look at the models with this one here.
04:59And here we are. I wanted to point out, again, Boris, such a short-lived little flicker in terms
05:05of its intensity for the future. And then here's Cristina. You'll notice that Boris basically just
05:09kind of disappears from the map into Tuesday after land interaction, if we look at the vorticity
05:14and the flow aloft. But Cristina is going to be with us here Thursday. There's an obvious sign
05:20there. You can see where Cristina is located. And then this may come in over southern parts of
05:24Guatemala. As we go to the European, just to find agreement or disagreement, there's pretty good
05:31agreement here. If there's a difference, GFS is a little faster with the landfall. And the European,
05:37I should say, the GFS is a little slower with the landfall, 2 p.m. on Thursday. The European would
05:44be faster by 2 p.m. Thursday, be over the land. But regardless, rainfall is the main concern. And
05:51here we are in inches. We're looking at over a foot of rain in parts of El Salvador. And again,
05:57we have our 8 to 12-inch zone in our map. But the big idea here is that we will
06:04see potential for
06:05locally over a foot. And our AccuWeather local storm max, while we are there,
06:12just to remind myself here, our AccuWeather local storm max is much bigger than the,
06:16we're looking at 24 inches of possible rain there in the worst case scenario. Now, beyond all that,
06:22in the Atlantic, we need to keep an eye out for around June 13th through 16th.
06:26A gradual increase in tropical moisture will be traversing parts of southern Mexico.
06:30It's an area of concern here. We do have some strong winds here in the short term over the
06:36central gulf into the sort of the northern half of the Caribbean. But we'll be watching
06:40some limited risk into the middle of the month.
